Quantum Gate

Researchers at QuTech developed somersaulting spin qubits for universal quantum logic. This achievement may enable efficient control of large semiconductor qubit arrays. The research group published their demonstration of hopping spins in Nature Communications and their work on somersaulting spins in Science.

The power of quantum machine learning algorithms based on parametrised quantum circuits are still not fully understood. Here, the authors report rigorous bounds on the generalisation error in variational QML, confirming how known implementable models generalize well from an efficient amount of training data.

The development of experimental platforms that advance the field of quantum science and technology (QIST) comes with a unique set of advantages and challenges common to any emergent technology. Researchers at Stony Brook University, led by Dominik Schneble, Ph.D., report the formation of matter-wave polaritons in an optical lattice, an experimental discovery that enables studies of a central QIST paradigm through…

A collaboration between computer scientists and physicists at the University of Chicago broke through one of the key obstacles for large-scale quantum computing by figuring out how to move their control signals "inside the fridge."

In a significant leap forward for quantum technology, researchers have achieved a milestone in harnessing the frequency dimension within integrated photonics. This breakthrough not only promises advancements in quantum computing, but also lays the groundwork for ultra-secure communications networks.

Researchers have succeeded in developing a technique to quickly search for the optimal quantum gate sequence for a quantum computer using a probabilistic method.

Enormous amounts of money have been invested into quantum computing, but so far it has not surpassed conventional computers. When will that change?

Ph.D. candidate Petr Steindl creates complex structures of light using single photons. As a teenager, he wanted to study Czech poetry but decided on quantum physics. "Looking back, I am glad I switched fields," he says. On July 5, he will defend his thesis on quantum optics and quantum dot systems.

New experiments put phonons — the tiniest bits of sound — into quantum mechanical superpositions and show they are as weird as other quantum entities.

Can quantum optics be used for practical applications? A lot depends on whether a large number of photons can be gathered in quantum state.
