«If you have strong coupling you can exchange quantum information between qubits, light, and particles, which can serve as quantum memory.»
At an extremely low temperature of around -273 degrees centigrade, magnons, i.e., quanta of the fluctuations in the magnet, coherently couple with the qubit through the electromagnetic field of the cavity.
He and his colleagues have taken a step toward such control, JILA's Bradley Moores told the meeting, by showing that they could simultaneously couple a single qubit to SAWs of several frequencies.
Importantly, it allows quantum bits (or «qubits»)-- the basic unit of information in a quantum computer — to be placed hundreds of nanometres apart and still remain coupled.
By coupling several qubits together on a D - Wave Two TM quantum optimizer, without changing the hardware of the device, these qubits act effectively as one qubit that experiences a lower temperature.
Although nearest - neighbour exchange coupling of two spins has been demonstrated, the interaction of spins via microwave - frequency photons could enable long - distance spin — spin coupling and connections between arbitrary pairs of qubits («all - to - all» connectivity) in a spin - based quantum processor.
The control over the electron wavefunction requires interfaces which lead to the loss of bulk properties of the qubit due to physical processes like the valley - orbit coupling, exchange, and many - body effects in coherent coupling.
