Russian researchers have reportedly built a 72-qubit quantum computer with a three-zone design that delivers 94 percent ...

The novel design for the new qubit uses the chemical element tantalum in tandem with a special silicon substrate, creating ...

Like their conventional counterparts, quantum computers can also break down. They can sometimes lose the atoms they ...

A shiny gray crystal called platinum-bismuth-two hides an electronic world unlike anything scientists have seen before.

Physicists have succeeded in coupling two Andreev qubits coherently over a macroscopic distance for the first time. They achieved this with the help of microwave photons generated in a narrow ...

Qubits are normally made from superconducting metals and need to be cooled to near absolute zero to avoid collapsing. But scientists just built an error-free "logical qubit" from a single laser pulse ...

Intel's quantum computing efforts are starting to show tangible results: two years after the company first unveiled its Horse Ridge cryogenic control chip, researchers have demonstrated that the ...

Quantum computers require extreme cooling to perform reliable calculations. One of the challenges preventing quantum computers from entering society is the difficulty of freezing the qubits to ...

Today, Google announced a demonstration of quantum error correction on its next generation of quantum processors, Sycamore. The iteration on Sycamore isn't dramatic ...

IonQ ( IONQ +4.39%) and Rigetti Computing ( RGTI +4.12%) are both well down from the highs they touched in October: IonQ is off by around 43%, while Rigetti is down about 60% from its peak. Could ...

Researchers in Australia have brought quantum computing up to a bewildering 1.5 Kelvin, which may not sound like much until you consider existing technologies require supercooling to almost absolute ...
