The University of California Santa Barbara has improved the integration of monolithic III-V lasers on silicon substrates.
To create silicon qubits, scientists trap a single electron in a tiny bit of silicon called a quantum dot. The value of the qubit — 0, ...
In a step forward for quantum computing in silicon — the same material used in today's computers — researchers successfully coupled a single electron's spin, represented by the dot on the left, to ...
Silicon quantum dots (QDs), on the other hand, show significantly improved light emission efficiencies, owing to quantum confinement effects. Nevertheless, the emission efficiencies of QDs are ...
Silicon quantum dots, also called artificial atoms, are the basic structure of silicon spin qubits. These tiny structures can trap and control individual electrons, allowing researchers to define ...
Silicon spin qubits store quantum information using the spin of an electron—a quantum version of a tiny magnet. These spins are confined in tiny structures called quantum dots, sometimes ...
Quantum computers could one day outperform traditional machines, but hurdles remain. Now physicists have successfully entangled three silicon quantum dots for the first time, in a breakthrough ...
