By combining surface codes with lattice surgery, researchers have shown how logical qubits can be manipulated and entangled ...

The qubit state decays toward the "north pole" of the sphere due to decoherence. Using the study's coherence-stabilized sensing protocol, the researchers temporarily counteracted the decay, leading to ...

A new theoretical study led by researchers at the University of Chicago and Argonne National Laboratory has identified the ...

Quantum Markov semigroups provide a rigorous mathematical framework for describing the time‐continuous evolution of open quantum systems. These semigroups encapsulate the interplay between coherent ...

Quantum researchers have deployed a new algorithm to manage noise in qubits in real time. The method can be applied to a wide range of different qubits, even in large numbers. Noise is the "ghost in ...

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 ...

Physicists have coaxed clusters of thousands of atoms into a delicate quantum limbo, creating a record breaking version of ...
