Quantum computing company Quantinuum has launched a new 56-qubit quantum computer. The company this week announced the launch of the H2-1, a quantum computer with 56 trapped-ion qubits. Not an ...

A quantum bit, otherwise known as a qubit, is the basic unit of data in quantum computing. Like a binary bit in classical computers, as it can store information, but behaves very differently thanks to ...

A new record has been set for extremely precise control over qubits, the building blocks of quantum computers. This advance could lead to quantum computers that make fewer errors – if it can be ...

The field of quantum computing has witnessed significant advances with superconducting qubits emerging as one of the most promising platforms for realising practical quantum processors. These systems ...

QuamCore Ltd, a startup working to develop a quantum computer with one million qubits, today announced that it has raised $26 million in early-stage funding. Sentinel Global led the Series A round ...

One small qubit, one giant leap for quantum computing The result foreshadows a leap in computational capabilities, leading researchers to reproduce the groundbreaking measurement. Date: July 24, 2025 ...

While the concept of quantum computing has been discussed for more than 40 years, only recently have experiments indicated that a practical quantum computer may be possible. Recent developments in ...

Quantum Art's new QPU could be both significantly smaller and also faster than competing quantum architectures. How can we reinvent quantum computing? Perhaps by shrinking it down and making it small: ...

The MarketWatch News Department was not involved in the creation of this content. -- IQM will deliver two IQM Radiance quantum computers to VTT in Finland: first a 150-qubit computer in 2026 and a 300 ...

The promise of so-called “quantum advantage” is simple. By harnessing the counterintuitive rules of quantum mechanics, quantum computers should be able to—in theory—surpass the computational potential ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.
