The promise of so-called “quantum advantage” is simple. By harnessing the counterintuitive rules of quantum mechanics, ...

CEA-Leti has developed an innovative superconducting interconnect brick that could enable achieving a higher density of ...

Normally, quantum computers store information using quantum bits, or qubits. However, to simulate the behavior of the molecules, we also used vibrations of the atoms in the computer called “bosonic ...

For all this to work, however, superconducting quantum computers need to be cooled to close to absolute zero (or -273.15 degrees Celsius).That makes machines like these among the coldest places in ...

They have proven, for the first time, that a quantum computer can generate bits of randomness that are certifiably random—verified using classical supercomputers.

The computer, called IBM Quantum Starling, will be housed in its Poughkeepsie, N.Y., center and have 20,000 times the computational power of today’s quantum computers, the tech giant said ...

Technology Quantum computers don’t always need more qubits – just add chaos. To create useful randomness in a quantum computer, you could add more quantum bits, but using quantum chaos does ...

Most quantum computers on the market usually process information using quantum states called qubits—fundamental units similar to a bit in a regular computer that can exist in two well-defined ...

In 2019, Google introduced Sycamore, a quantum computer capable of calculations that would take 10,000 years to run on the world’s leading supercomputer.

Super-powered quantum computers could upend the cryptocurrency system. The solution would require cryptocurrency to slow itself. But that comes at a cost.

Quantum computing stocks are shares of companies involved in the development of next-generation computers. Here are the 7 best performers.

Using a powerful machine made up of 56 trapped-ion quantum bits, or qubits, researchers have achieved something once thought impossible. They have proven, for the first time, that a quantum ...
