This new startup has built a record-breaking 256-qubit quantum computer
QuEra Computing, a Boston startup emerging from stealth, to show off the programmability of their 256-qubit quantum simulator—a special-purpose quantum computer built for solving certain types of problems.

The atom advantage
QuEra’s machine was built from a blueprint and technologies refined over several years, led by Mikhail Lukin and Markus Greiner at Harvard and Vladan Vuletić and Dirk Englund at MIT (all are on QuEra’s founding team). In 2017, an earlier model of the device from the Harvard group used only 51 qubits; in 2020, they demonstrated the 256-qubit machine. Within two years the QuEra team expects to reach 1,000 qubits, and then, without changing the platform much, they hope to keep scaling up the system beyond hundreds of thousands of qubits.

I dont see any Chinese names there... Funny that. Guess its upto the Caucasians once again to define and invent the worlds best stuff.

It's very likely that it's a scam like most "revolutionary" start-ups these days

I don't know anything about it, I'm just basing my opinion on pure statistical probability

Record breaking?

Over 2 years old now...

You better believe Geordie has 10kq+ now, especially with Google in the mix.

Quantum Simulator not quantum. IBM hit 127 fully entangled qubits 2 weeks ago

Re: This new startup has built a record-breaking 256-qubit quantum computer
"QuEra’s platform uses arrays of neutral atoms that produce qubits with impressive coherence (that is, a high degree of “quantumness”). The machine uses laser pulses to make the atoms interact, exciting them to an energy state—a “Rydberg state,” described in 1888 by the Swedish physicist Johannes Rydberg—at which they can do quantum logic in a robust way with high fidelity. This Rydberg approach to quantum computing has been worked on for a couple of decades, but technological advances—for instance, with lasers and photonics—were needed to make it work reliably".
