Why I dislike what “quantum supremacy” is doing to computing research

Why I dislike what “quantum supremacy” is doing to computing research

Photons are (almost) supreme — Another quantum computing architecture closes in on quantum supremacy. Chris Lee - Dec 23, 2019 6:45 pm UTC Enlarge / This optical setup is not your friend. Many fast switches and delay lines set up to arrange for 20 photons to enter the waveguide circuit simultaneously.The big quantum buzzword these…

2019 was a huge year for quantum computing – The Next Web

2019 was the biggest year for quantum computing since, well, ever. It’s the year IBM put a quantum computer in a box and Google claimed its Bristlecone system reached quantum supremacy. But perhaps most exciting was the incredible research happening in universities and think-tanks around the globe. From warp drives to time travel, scientists around…
Quantum computing’s also-rans and their fatal flaws

Quantum computing’s also-rans and their fatal flaws

Where are they now? science style  — When it comes to performance, engineering matters more than physics. Chris Lee - Nov 30, 2019 3:00 pm UTC Enlarge / IBM's 16-qubit quantum computer from 2017.Last month, Google claimed to have achieved quantum supremacy—the overblown name given to the step of proving quantum computers can deliver something…

Quantum computers learn to mark their own work – Phys.org

Credit: CC0 Public Domain A new test to check if a quantum computer is giving correct answers to questions beyond the scope of traditional computing could help the first quantum computer that can outperform a classical computer to be realized. By creating a protocol that allows a quantum computer to check its own answers to…

A knotty conundrum — Research has implications for future topological quantum computers. Jennifer Ouellette - Nov 15, 2019 8:10 pm UTC Enlarge / Researchers captured the decay of a quantum knot (left), which untied itself after a few microseconds and eventually turned into a spin vortex (right).Tuomas Ollikainen/Aalto UniversityThe same team who tied the first…

The quantum supremacy enigma: Can Google’s claim withstand scrutiny? – ZDNet

If quantum computing is ever to transcend the realm of experiment and become a legitimate industry, it will need to sustain a legitimate business model. Businesses invest in machines and technologies — or, in the case of the cloud, in the services that provide them — when they have become reliable. They function as their…

IBM vs. Google and the race to quantum supremacy – Salon

This Feb. 27, 2018, photo shows a seven cubit quantum device is seen at the IBM Thomas J. Watson Research Center in Yorktown Heights, N.Y. Conventional computers process information as a stream of bits, each of which can be either a zero or a one in the binary language of computing. But quantum bits, known…

The Quantum Computing Threat to American Security – The Wall Street Journal

Google announced last month that it had achieved “quantum supremacy,” demonstrating the potential of a new kind of computer that can perform certain tasks many orders of magnitude faster than the most advanced supercomputers. It’s a crucial moment for America’s national security, which depends on winning the race to do what quantum computers will do…
Quantum mechanics gets stern challenge from single silicon ion

Quantum mechanics gets stern challenge from single silicon ion

G-factor misses the spot  — Spiraling ion probed for months, revealed g-factor not quite as predicted. Chris Lee - Nov 8, 2019 3:40 pm UTC The world of physics is a bit like a child's bedroom. After sufficient yelling, everything becomes neat and tidy, but open a drawer or look under the bed and an…

The Morality of Quantum Computing

This morning a humanities teacher named Richard Horan, having read my NYT op-ed on quantum supremacy, emailed me the following question about it: Is this pursuit [of scalable quantum computation] just an arms race? A race to see who can achieve it first? To what end? Will this achievement yield advances in medical science and…

NASA restores Apollo Mission Control to its 1969 Moon landing condition

To celebrate the 50th anniversary of the Moon landing, which is coming up on July 20, NASA has restored and re-opened the original Apollo Mission Control Center at Johnson Space Center in Houston. The restoration is a painstakingly detailed recreation, which involved years of research of archival footage and photography, and seven months of restoration…
