New Qubits for Quantum Computers Using Vibrating Atoms Discovered

Quantum Computing is changing fast in 2022.

This week a lot has happend in Quantum Computing, so much in fact I’m nearly starting to think of dedicating an entire Newsletter to it.

So much is happening in Quantum Computing I've decided to make a new Newsletter on it called Quantum Foundry where I will be covering the industry, companies, IPOs and breaking news. You can join it here:

• Canadian quantum computer pioneer D-Wave to go public on NYSE in US$340-million SPAC deal. D-Wave Systems Inc. has become the latest quantum computer developer to pursue a public listing through a merger with a special purpose acquisition company (SPAC) which is not surprising considering their lack of real clients.
• More articles on the debate of how?quantum computing will break Bitcoin (and Internet)?encryption likely in the next 10-years.
• Quantum Motion?(London based) wants to?build world’s most powerful computer?(them and dozens of other Quantum computing startups).

However I think the News that caught my intention the most was the New Qubits story.

• MIT physicists have discovered a new quantum bit, or “qubit,” in the form of vibrating pairs of atoms known as fermions.
• They found that when pairs of fermions are chilled and trapped in an optical lattice, the particles can exist simultaneously in two states — a weird quantum phenomenon known as superposition.
• In this case, the atoms held a superposition of two vibrational states, in which the pair wobbled against each other while also swinging in sync, at the same time.

Quantum computing as it scales will provide A.I. with many more possibilities in the next few decades.

The MIT Team was able to maintain this state of superposition among hundreds of vibrating pairs of fermions. In so doing, they achieved a new “quantum register,” or system of qubits, that appears to be robust over relatively long periods of time. The discovery, published on January 26, 2022, in the journal?Nature, demonstrates that such wobbly qubits could be a promising foundation for future quantum computers.

The 2022 Qubit

So why is this important?

The MIT team’s new qubit appears to be extremely robust, able to maintain a superposition between two vibrational states, even in the midst of environmental noise, for up to 10 seconds. The team believes the new vibrating qubits could be made to briefly interact, and potentially carry out tens of thousands of operations in the blink of an eye.

Potential Quantum Computing Breakthrough

• In this state, a qubit should be able to communicate with other qubits and process multiple streams of information, to quickly solve problems that would take classical computers years to process.
• To make a functional quantum computer using vibrating qubits, the team will have to find ways to also control individual fermion pairs.

“We estimate it should take only a millisecond for these qubits to interact, so we can hope for 10,000 operations during that coherence time, which could be competitive with other platforms,” says Martin Zwierlein, the Thomas A. Frank Professor of Physics at MIT. “So, there is concrete hope toward making these qubits compute.”

Summary

Published in Nature, the research provides a doubling of the previous quantum coherence record, an already impressive achievement from just last week. The new record stands atop the discovery of a new form of qubits, based on vibrating pairs of atoms — also known as fermions.

The team’s work focused on investigating the behavior of fermions (essentially atoms with odd half-integer spins). The fermions kept drifting in and out of the lattice’s observable area at periodic intervals, almost like pendulums, swinging inside and outside of the observable area. This, in turn, indicated that they were oscillating between two quantum states — one observable and the other not.

Addendum

More Quantum Computing startups are getting funding in 2021 and 2022 than ever before. The D-Wave SPAC is evidence of the hype, even though for most this startup is already considered a business failure.

IonQ is a quantum computing hardware and software company based in College Park, Maryland that has a stock price of $13 and a market cap of $2.5 Billion but there are literally dozens of Quantum startups worth watching.

Quantum Motion (pictured above) has recently in early 2022 opened a new quantum lab in London, to develop a quantum computer using silicon chips. Based in Islington, north London, the facility will employ 25 full time staff, including quantum theorists, physicists and Integrated Circuit (IC) engineers.

That Quantum computing in silicon hits 99% accuracy is itself a major breakthrough that’s recent. Australian researchers have proven that near error-free quantum computing is possible, paving the way to build silicon-based quantum devices compatible with current semiconductor manufacturing technology.

Finally if you want to tip or offer patronage I cannot continue to write without community support. I plan to further build out this newsletter with IPO, M&A and specialized due diligence reports on newer fields like Quantum computing, genomics, 3D-printing and Space technology that will likely be called?Quantum Foundry.

Since this is a passion project and my only source of income and just at the start, I'm often working weekends as well.
