However, the quantum states they rely on are prone to decohering – that is, losing their quantum information due to local noise. One possible way around this is to use quantum bits (qubits) ...

David Reilly and his University of Sidney team developed a silicon chip that can control spin qubits at milli-kelvin temperatures. That’s just slightly above absolute zero (-273.15 degrees Celsius), ...

Quantum computers use qubits, which are based on quantum physics, allowing them to solve complex problems far faster than ...

Researchers at Chalmers University of Technology in Sweden have developed a highly efficient amplifier that activates only when reading information from qubits. Quantum computers can solve ...

Researchers at QuTech in Delft, The Netherlands, have developed a new chip architecture that could make it easier to test and scale up quantum processors based on semiconductor spin qubits. The ...

Quantum computers can solve extraordinarily complex problems, unlocking new possibilities in fields such as drug development, encryption, AI, and logistics. Now, researchers at Chalmers University of ...

Developing technology that allows quantum information to be both stable and accessible is a critical challenge in the development of useful quantum computers that operate at scale. Research published ...

Diamond color centers are a well researched field, but using them at scale as qubits was out of reach until recently. Their Quantum Transistor device (patent pending) resolves the charge stability ...

Quantum computers made from qubits based on extremely cold atoms have been getting larger at an impressive rate, which may soon make them computationally powerful – but errors arise at a rate that ...

The commonly used RSA encryption algorithm can now be cracked by a quantum computer with only 100,000 qubits, but the technical challenges to building such a machine remain numerous ...
