In quantum computing, a Greenberger–Horne–Zeilinger (GHZ) state is a special type of entangled state involving three or more qubits that are perfectly correlated across all qubits.

IBM (IBM) on Tuesday said it is building the world's first large-scale quantum computer capable of operating without errors. The computer, called Starling, is set to launch by 2029. The quantum ...

The quantum computer, called Starling, will use 200 logical qubits — and IBM plans to follow this up with a 2,000-logical-qubit machine in 2033 ...

IBM today launched the Qiskit Functions Catalog, a new set of services that aims to make programming quantum computers easier by abstracting away many of the complexities of working with these ...

Officials on Friday announced the deployment of the first IBM Quantum System One computer on a university campus, at Rensselaer Polytechnic Institute in upstate New York. It’s aimed at driving ...

IBM is planning to build the largest quantum computer so far, by linking together smaller machines to create one with a recording-breaking number of quantum bits, or qubits. The firm’s first ...

Unsurprisingly, IBM feels that Qiskit did extremely well on its tests, but the details provide a window into where things stand in the world of quantum-computing software stacks, as seven ...

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.

IBM has already made a whole fleet of quantum computers, but the path towards a truly useful device isn’t straightforward – nor is it devoid of competition. Errors continue to spoil many ...

DARPA and IBM also will have facilities at the quantum park, with the state kicking in $25 million to purchase equipment and make preparations to house IBM’s new quantum computer.

IBM announced detailed plans today to build an error-corrected quantum computer with significantly more computational capability than existing machines by 2028. It hopes to make the computer ...
