The public exhibits a generally optimistic outlook on India's achievements in quantum communication, showcasing pride in scientific advancements. However, there are notable concerns regarding the effectiveness of presentations, comparisons with global counterparts like the USA and China, and skepticism towards the application of these breakthroughs in defense technology. Mixed feelings arise from optimism for future prospects juxtaposed with criticism about the current state of India's defense capabilities.

how is quantum entanglement coming into play here

Majestic_Explorer231

photo mai to bas laser se data transmit kiya tha, isme quantum entanglement wala part samjh nhi arha

MaiAgarKahoon3

Left to themselves IIT and DRDO can do great things in R&amp;D.

Get the IAS approval for commercial scale production or deployment for defence services that's going to take another 100 years before neither IIT or DRDO have money to pay the IAS for approval

# Defense and National Security

* **Military-grade communication**: Think nuclear command-and-control, drone communications, and submarine networks secured with quantum encryption.
* **Counter-espionage**: Traditional encryption can be cracked in the future by quantum computers; QKD offers a defense against this.

# Civilian Applications: What’s Coming?

* **Banking**: Secure ATMs and inter-bank transfers immune to quantum decryption.
* **Healthcare**: Protect patient records and drug research IP.
* **E-Governance**: Protect biometric data in Aadhaar, voting systems, or tax databases.

We are still miles behind, and this kind of experiments have been done multiple times in India too at RRI banglore, PRL ahmedabad, IIT madras. What makes tbis special is they have done it in free space with a large keyrate which might be a step forward in right direction

Alice &amp; Bob are interesting. But there's so many to keep an eye on that are worth the effort to do so. Horizon Computing, Classiq Technologies, Quantum Brilliance, Q-CTRL, OQC, etc. 

The more specific question you ask is if there is any chance of a smaller venture competing with the entrenched FAANG companies? This is a fair question, as the SaaS and Cloud era saw greater monopolisation building up, which has arguably been on display in the current AI phase. Although the role of antitrust measures has forced some moves that otherwise wouldn't have occurred (e.g. Microsoft in Europe, acquihires rather than acquisition sprees, partnerships, etc). 

Quantum computing is a little different in the nature of emerging from regions with strong academic R&amp;D activity. This is fascinating to see, as you wouldn't otherwise expect Canada and Australia to be so high in the leadership of this area, along with the Swiss, German, French, etc. The nature of capital deployment accounts for the Seed to Series-A stages, with university resources giving way to government grants and funds/co-funding, and local venture capital. We've seen the sovereign funds kicking into gear as global VC moved to focus on AI, and it makes sense that governments would be investing into quantum given the rise of geopolitical tensions.

So that's some context, and you can imply that regions with good universities and quantum physics talent, along with government support of Deep Tech, have a certain pool of talent and potential. So let's look at the other side of the question. The existing companies. 

* Google - really interesting team that stays focused on their large-scale architecture and benefits towards AI and ML. 
* IBM - clever rebrand and repositioning around their System Two and laser focused on big business and fault tolerant (while building out their community moat).
* Microsoft - there's a lot of changes happening here right now, and the chatter here in Seattle points to a number of big moves being made, so stay tuned I guess.
* Meta - focused on other areas. 
* Apple - no idea, but I know a bunch of their AI management have left to join stealth quantum startups. 

  
As ever, the advantage startups have is speed, focus, and room to experiment or take risks outside of the larger organisational power dynamic. Some of my team when I was at Quantum Brilliance were formerly of IBM and while they still struggled to let go of "the old ways", they had absolutely incredible experiences we could draw from. The bar for Deep Tech startups is pretty high now, and the ability to lobby and do deals on the sovereign scale is impressive (see PsiQuantum's deals in Australia and Illinois). 

TLDR: IMHO the more interesting innovations will come from the startups, although I'm biased as I work for one, and the major FAANG companies are focused on very long term fault-tolerant scale. Expect the usual waves of startup shutdowns and layoffs over the next few years, and acquisitions to kick in as the landscape becomes clearer.

Quantum computing exists purely in research at the moment. Yes there are people working on applications and on hardware, but no one has an actual path towards long term profitability, including large companies. Saying "industry" is a huge misnomer, because these companies are not necessarily trying to market anything. 

The reason so many small companies exist is essentially because there is no real funding in academia. Being a R&amp;D dominated field, there are very few qualified people and those who are tend to have tenured positions at universities. Still, they need funding to the tune of millions of dollars to build a prototypes. Universities don't have the budget, so venture capitalists step in. 

The goal for the company is to own the technology that researchers come up with, and researchers need capital to fund experiments and so on. Startups are created so that some entity can own the patents and IP that researchers produce, in return for the funds to actually create the tech. There is huge value in solving problems that are preventing us from building fault tolerant quantum computers, even if the startup itself may or may not be the one to build it.

- Have they made significant progress?  
The short answer is "no" if you are interested in something that is useful for industry or society. However, one can discuss about the need to do basic and fundamental research before getting anything commercially useful. From this point of view, a lot of effort has been put and a lot of answers have been provided for problems that would be probably appealing for physicists mostly. I don't know what is your background and if you are interested.

- Related to the previous question, the technological progress has been huge. We are now able to realize and control very large quantum devices (up to thousands of qubits). This results has been possible thanks to both academia and industry, however the largest and most efficient ones are usually industrial platforms (QuEra,Google Quantum AI,IBM,IQM,Pasqal,DWave,...).   
  
- I am not aware of any notable advance if you are interested in something that could be considered useful for society.   
However, all the above mentioned companies (and many more), with the exception of QuEra and Google that have tight academic connections and do mostly fundamental research,  are focusing on  quantum solutions to problems that could be appealing to a broad audience (e.g. portfolio optimization, drug discovery, vehicule routing and so on)

Source: I have been an academic researcher in the field for 6 year (worked with IBM and Google) and I am currently a researcher for a European quantum company.

Yes, though Alice and Bob don't have a working chip yet. (They require a string of 20+ Josephson junctions which is hard to manufacture)

But, so called "open stack" producers, are poised to outperform the full stack manufactures within 2 to 4 years. 

The reason is simple, and is apparent from every single modern day company too: specialization. By focusing on just 1 elemen of the stack, advancements are made much faster. For countries building up knowledge there is much more to gain from an open stack, than a closed stack. So national quantum computers are more likely to be open stack.

There is hundreds of start ups and scale ups, in different modalities, and different parts of the stack. If you can narrow that down I can give you some references

IONQ is doing pretty good, there are many posts about them.

UrinaryButanohole

stand a chance at what exactly?  nothing is happening for anyone.  money is not being converted into results.  it is lost to wishful thinking and general crankery.

we haven't solved anything with quantum computing better than classical and never will.

downvote if you drank the koolaid.

Can you imagine if we could collect ad revenue from multiple universes?

Love all the stupid fearmongering...

&gt;Something from another universe may be aware of us.

Yeah, like *every other one of the infinitely many versions of us that likes the Many-Worlds Interpretation*.

&gt;Are We Being Watched?

Ask Edward Snowden.

&gt;The Mandela Effect (collective false memories) could be caused by reality shifts from quantum interactions.

It couldn't.

&gt;Could advanced civilizations from parallel universes already be aware of us?

It could be as bad as the MCU and DCU *combined*!

&gt;If quantum computers are detecting external signals, could this mean we are in a simulated reality?

So now it's just not at all about parallel universes anymore.....?

&gt;A researcher allegedly stated, “We made contact. It wasn’t supposed to happen.”

Another researcher allegedly stated "The brain eaters from Mars are coming for our tacos!" This was alleged by me.

&gt;Could we have accidentally weakened the barriers between dimensions?

Not at all how that works. Read a book, goodness gracious.

&gt;Unexplained anomalies, such as time glitches and reality shifts, are being reported worldwide.

They aren't.

&gt;Has the government known about the Multiverse all along?

Half the US government doesn't even believe in *vaccines*.

&gt;Did Google’s quantum chip alter our reality, and have we already felt the effects?

The "effects" being posts on r/SimulationTheory 

&gt;Quantum computing might destabilize our universe.

Just to make it very clear, and to be serious for a second: Literally everything is quantum. Look at your hand: That's 10 trillion trillion atoms, every moment there's trillions of trillions of trillions of infinities of interactions described by quantum physics within them and between them. And that happens in the entire universe, constantly, at all times.  
So one quantum computer will not be the thing that destroys our world.

Where is the link or doi of the Google team's paper?

Short answer: No

Long answer: You might want to watch the explanation by Sabine Hossenfelder on this topic.

Pretty sure this OP is a bot or paid poster or something. they posted a video yesterday and this post is literally just the transcript of that video.

I sent the video to r/physics and they debunked it.

Lots of experiments with quantum computers from various countries over years have detected new things imo not just Google. The one I like is the one where scientists converted the Fibonacci sequence into laser flashes via a quantum computer and they discovered new forms of measuring matter in different states. Maths can create something from nothing in a vacuum and the stuff talking back is probably as a vacuum is never fully empty, there is always something in nothing, some call it zero point energy others dark energy, the people who figure out how to make money out of nothing are going to be controlled by money people in our reality, bombs and medicine work together in our reality.

Like bad reality tv, probably has terrible ratings in the streaming multiverse.

What id like to know is how are other countries responding, considering every known encryption is cracked now.

Multiple realities exist, you can even change realities yourself with your mind.

I've witnessed a ton of "timeline shifts" since that can of worms was opened. Super odd one is the preferred cheese at work until then has always been American. It's now provolone by an enormous margin. Used to be one or two a week, if that.
