Quantum dots are microscopic semiconductor crystals developed in the lab that share many properties with atoms, including the ability to absorb or emit light, a technology that Los Alamos researchers ...

“Graphene quantum dots, first recognized in 2007, emerged as interesting hosts for spin qubits, which can employ both electron and hole quantum dots to facilitate long-range coupling,” he says. Holes ...

A new method preserves spin qubits up to ten times longer. Hole spins, rather than electron spins, can keep quantum bits in the same physical state up to 10 times longer than before. The holes within ...

Physicists in recent years have been pursuing a variety of routes to tap electron spins for their potential use in quantum computers that can perform millions of computations at a time and store ...

Scientists at TU Delft have unlocked a key quantum effect in graphene without using any magnetic fields, paving the way for ...

Could the future of clean energy hinge on the spin of a single electron? A new scientific review suggests it might.

Spin-Orbit Effects on Exciton Complexes in Diamond. Physical Review Letters, 2024; ... electron-hole pairs confined in moir interference fringes which overlap with slightly offset patterns ...

WEST LAFAYETTE, Ind. — By using photons and electron spin qubits to control nuclear spins in a two-dimensional material, researchers at Purdue University have opened a new frontier in quantum science ...

PORTLAND, Ore. — Researchers gathered this week to extend the use of quantum effects in semiconductors. Quantum effects result from the confinement of electrons, or holes, by restricting their free ...

The quantum fix. Famed Danish physicist Niels Bohr was the first person to propose a solution to this issue. In 1913, he suggested that electrons in an atom couldn't just have any orbit they wanted.
