Explore the competition between Google's surface codes and IBM's QLDPC codes in the race to achieve fault-tolerant quantum ...

This announcement comes at a time when Google has faced criticism for slowing down in innovation and losing relevance, ...

Chinese scientists have unveiled Zuchongzhi 3.0, a 105-qubit quantum processor that puts China on par with the United States in the race to build the world’s most powerful quantum computer.

The operation falls apart if researchers do anything at all to observe the state of a qubit while it's working. Austrian physicist Erwin Schrödinger famously compared this concept to having a cat ...

Specifically, we are working on designing quantum materials featuring exotic quantum phenomena, including unconventional superconductivity, symmetry-broken states, topological states, unconventional ...

Google's Willow quantum chip, with 105 qubits, enhances AI and quantum applications, boosting sentiment. Despite competitors IBM (156 qubits) and Microsoft (topological qubits), Google leads when ...

A physical qubit only lasts for billionths of a second, and so its lifetime isn't long enough for the "decoder" circuitry of the quantum machine to read its information. The logical qubit ...

There was a time, back in the early days of computing, when we had vacuum tubes, relays, mechanical gears plus several different types of analog computers. We’re kind of in that same era today ...

Having just crossed the 1,000-qubit mark, today’s devices area a long way off, but more importantly their qubits are incredibly unreliable. The devices are highly susceptible to errors which can ...

The DRQ (Dual Rail Qubits) are double superconducting cavities. They encode one qubit in the single-photon subspace of two superconducting microwave cavities. One cavity represents the logical ‘0’ ...
