In a recent study, researchers at the University of Colorado have resolved phonon Fock states in the spectrum of a superconducting qubit coupled to a multimode acoustic cavity. Fock states (or number states) are quantum states ...
Quantum information platforms are based on qubits that talk to each other and photons (optical and microwave) are the carrier of choice—to date, to transfer quantum states between qubits. However, in some solid-state systems, ...
Thermoelectric devices are highly versatile, with the ability to convert heat into electricity, and electricity into heat. They are small, lightweight, and extremely durable because they have no moving parts, which is why ...
