Electronic spin storage in an electrically readable nuclear spin memory.

Nuclear spin Memory Logic 1. Introduction The advance of semiconductor technology over the last four decades is often represented by Moore's law which predicted the approximate doubling of switches or transistor devices in an integrated circuit nearly every 18 months.

Implementation of the nuclear spin memory Our two-qubit sensor exploits the four-level system formed by the m S ∈ {0, −1} subspace of the S = 1 electronic spin and the two m I ∈ {−1/2, +1/2} states. The result is that the electron spins and nuclear spins match—the spin information has effectively been encoded in a longer-lived nuclear memory. So even if the electron itself loses its memory,. The state is left in the nuclear spin on a timescale that is long compared with the electron decoherence time, and is then coherently transferred back to the electron spin, thus demonstrating the 31 P nuclear spin as a solid-state quantum memory. The overall store-readout fidelity is about 90 per cent, with the loss attributed to imperfect.

Nuclear spin-wave quantum register for a solid-state qubit.

Storing information in a nuclear spin will likely require an electron-nuclear double resonance technique as demonstrated in P:Si [116], but other nuclear spin memory experiments have been proposed.

We use two carbon nuclear spins coupled to the processor electron spin as auxiliary memory qubits. All nuclear spins can be individually manipulated with the help of hyperfine interactions with the.

A system comprising a solid state lattice containing an electronic spin coupled to a nuclear spin; an optical excitation configuration which is arranged to generate first optical radiation to excite the electronic spin to emit output optical radiation without decoupling the electronic and nuclear spins; wherein the optical excitation configuration is further arranged to generate second optical.

We further show that nuclear-spin polarization enables the use of well-known methods for initialization and long-time coherent storage of quantum states. The proposed nuclear-spin preparation protocol thus marks the first step towards an all-optically controlled integrated platform for quantum technology with TM defects in SiC. Publication.

Nuclear spins are an obvious candidate for implementing such a memory, because they tend to have extremely long spin lifetimes ( 1 - 3 ). To date, implementations of quantum logic or memory devices directly involving nuclear spins have used optical or microwave detection in systems such as the nitrogen vacancy center of diamond ( 4 - 6 ).

This method promises a wide range of applications in other spin-based systems. Nuclear spins are attractive candidates for quantum information processing because of their extremely long coherence time, e.g., the long-lived quantum memories for preserving the multi-qubit entanglement, 1-5 1. F.

Thus, according our theory, the nuclear spin ensembles are the "mind-screen" with nuclear spins as its pixels, the neural membranes and proteins are the mind-screen and memory matrices, and the biologically available paramagnetic species such as O2 and NO are pixel-activating agents. Together, they form the neural substrates of consciousness.

A sensor able to detect such magnetic fields with nanometre spatial resolution would enable powerful applications, ranging from the detection of magnetic resonance signals from individual electron or nuclear spins in complex biological molecules to readout of classical or quantum bits of information encoded in an electron or nuclear spin memory.

The electronic spin information can be mapped onto and stored in the nuclear spin of the phosphorus donors, and the nuclear spins can then be repetitively read out electrically for time periods that exceed the electron spin lifetime. We discuss how this memory can be used in conjunction with other silicon spintronic devices. PMID: 21164011. Here, we use the NV intrinsic nuclear spin as a nonvolatile classical memory to store NMR information, while suppressing sensor back-action on the target using controlled decoupling of sensor,. Spin resonance techniques are generally used for control. Nuclear-spin-based quantum memory. The quantum bits created in diamond by Maurer et al. and in silicon by Steger et al. can both be read out optically, and both couple to nearby nuclear spins, which can be used as a long-lived quantum memory.

US9361962B2 - Solid-state quantum memory based on a nuclear spin.

Recently, an ensemble of nuclear spins in a quantum dot have been proposed as a long-lived quantum memory. A quantum state of an electron spin in the dot can be faithfully transfered into nuclear. These nuclear spins can be polarized and fully controlled and provide a robust quantum memory, even in the presence of optical radiation necessary for electronic spin-state readout (13, 22). This is achieved through a combination of optical, microwave, and RF fields (Fig. 1) and is discussed in (25). Fig. 1Repetitive readout of an electronic spin.

The suitability of the nuclear spin as a quantum memory element depends more critically on the nuclear coherence time, T2n, the measurement of which has now been made possible through the storage. The possibility that quantum processing with nuclear spins might be operative in the brain is explored. Phosphorus is identified as the unique biological element with a nuclear spin that can serve as a qubit for such putative quantum processing-a neural qubit-while the phosphate ion is the only possible qubit-transporter.We identify the "Posner molecule", Ca 9 (PO 4) 6, as the unique.
