Google Promises a Usable Quantum Computer in 2029

The WSJ reported a couple of months ago:

Google scientist Hartmut Neven said the company intends to invest several billion dollars to build a commercial-grade quantum computer that can perform large-scale, error-free business and scientific calculations by 2029.

Google's Sundar Pichai announced the project's timeline, and unveiled the new Google Quantum Artificial Intelligence (AI) campus in Santa Barbara County, CA, to develop the system.

The Internet search giant aims to deliver commercial-grade quantum-computing services over the cloud, while Neven said the company envisions applications ranging from building more energy-efficient batteries to accelerating training for machine learning AI.

Google said such applications will require a 1-million-quantum bit (qubit) computer.

Neven said one of the technical challenges will be to extend the length of time that a qubit can remain in its quantum state.

I doubt it, but this blog may not still be watching the issue in 2029.

This sounds like an impressive Google commitment, but there is a very long list of Google ambitions that have been abandoned. See Killed by Google for a list of 240 of them.

I got this article from the top US computer scientist association, and I see that they are gone anti-White in another article:

In June 2020, a community of Black people in computing from around the world published an open letter,a initiated by the authors, and a call for actionb to the global computing community. The letter began with, "The recent killing of George Floyd by Minneapolis Police has sparked a movement that began at the birth of our nation. Though George Floyd may have been the most recent instance, we should not forget the lives of Breonna Taylor, Ahmaud Arbery, Nina Pop, Tony McDade, Sandra Bland, Trayvon Martin, Aiyana Stanley-Jones, Philando Castille, Tanisha Anderson, Atatiana Jefferson, Eric Garner, Charleena Lyles, Eula Love, Michael Brown, Khalif Browder, Botham Jean, Tamir Rice, Latasha Harlins, Amadou Diallo, Mary Turner, Emmett Till, and too many other Black people who have been murdered …"

At the time, we reflected on this history of the killing of Black people in the U.S. and noted that these killings not only show the ultimate outcomes and harms that racist systems and institutions have on Black people, but they also spotlight the constant emotional and psychological strain that Black Americans endure. The accumulated experience of the Black computer science community highlights the magnitude of injustices that countless members of our community experience.

No, this is nonsense. I watched the Trayvon Martin trial on TV, and it was convincingly proved that he was not murdered. I watched the George Floyd trial also, and no evidence was even presented that race had anything to do with his death. If anything, the stories of George Floyd and others spotlight the constant strain Black felons and junkies put on our society.

Today, we are issuing another call to action to the individuals, organizations, educational institutions, and companies in the computing ecosystem to address the systemic and structural inequities

The ACM has no business raising these issues, but since it is demanding that these issues be addressed, I should say that it is all a big hoax, and that all of the racism is to the benefit of Blacks.

Officially, the US NSA is not worried about quantum computers:

Q: Is NSA worried about the threat posed by a potential quantum computer because a CRQC exists?

A: NSA does not know when or even if a quantum computer of sufficient size and power to exploit public key cryptography (a CRQC) will exist.

And it is negative about quantum key distribution:

Q: Are QKD systems unconditionally secure?

A: No. While there are security proofs for theoretical QKD protocols, there are no security proofs for actual QKD hardware/software implementations. There is no standard methodology to test QKD hardware, and there are no established interoperability, implementation, or certification standards to which these devices may be built. This causes the actual security of particular systems to be difficult to quantify, leading in some cases to vulnerabilities.

Q: Should I use a QKD system to protect my NSS from a quantum computer?

A: No. The technology involved is of significant scientific interest, but it only addresses some security threats and it requires significant engineering modifications to NSS communications systems. NSA does not consider QKD a practical security solution for protecting national security information.

This seems right to me. I have posted here many times that QKD has no practical value, despite the many millions going into it, and the proponent claims that it is the only provably secure cryptography.

The NSA looks 20 years ahead, and is keeping tabs on progress in quantum computers, and in defending against them. If it really htought that Google would have a commercial quantum computer with a million qubits in 2029, then it would be already converting to a quantum-resistant cryptography. Based on this FAQ, it see a quantum computer as speculative, and in the distant future, if at all.
