Long-lived quantum memory with nuclear atomic spins.
We propose to store nonclassical states of light into the macroscopic collective nuclear spin (10(18) atoms) of a 3He vapor, using metastability exchange collisions. These collisions, commonly used to transfer orientation from the metastable state 2 3S1 to the ground state of 3He, can also transfer quantum correlations. This gives a possible experimental scheme to map a squeezed vacuum field st...
متن کاملLong-lived qubit memory using atomic ions.
We demonstrate experimentally a robust quantum memory using a magnetic-field-independent hyperfine transition in 9Be+ atomic ion qubits at a magnetic field B approximately = 0.01194 T. We observe that the single physical qubit memory coherence time is greater than 10 s, an improvement of approximately 5 orders of magnitude from previous experiments with 9Be+. We also observe long coherence time...
متن کاملNuclear Spins as Quantum Memory in Semiconductor Nanostructures
We theoretically consider the possibility of using solid state nuclear spins in a semiconductor nanostructure environment as long-lived quantum memory. In particular, we calculate, in the limit of a strong applied magnetic field, the quantum coherence time for P donor nuclear spins in random bath environments of Si and GaAs, and the lifetime of excited intrinsic spins in polarized Si and GaAs e...
متن کاملQuantum Computing with Nuclear Spins in Semiconductors
The successful implementation of a scalable, fault-tolerant quantum computer would introduce a type of information processing more powerful than any available today. Reciprocally, the discovery of a fundamental obstacle to such a system would be an important advance in the foundations of quantum theory. No such fundamental obstacles are currently known, but neither has any architecture been sho...
