Spin-mediated consciousness theory: possible roles of neural... - PubMed.

We demonstrated an ensemble nuclear spin memory in phosphorous-doped silicon, which can be read out electrically and has a lifetime exceeding 100 seconds. The electronic spin information can be. To this end, we investigate the application of the intrinsic nitrogen nuclear spin (below called memory spin) for robust intermediate storage of classical metrology information. The nonvolatile classical memory furthermore allows decoupling of target spins from the sensor thus closing the decay channel. 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.

Quantum cognition: The possibility of processing with nuclear spins in.

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. In materials with only a small percentage of spinful isotopes, the long coherence times of nuclear spins have already been exploited to create a quantum memory. For example, quantum information.

On the other hand, dynamic nuclear polarization enabled by the hyperfine coupling between the electron and nuclear spins can be utilized as a memory resource [46, 53] or even as a rechargable spin.

Nuclear-Spin Quantum Memory Poised to Take the Lead.

Here, we present experimental data on a quantum memory consisting of a single 13 C nuclear spin that is strongly coupled to the electron spin of a nitrogen-vacancy (NV) center in diamond. The strong hyperfine interaction of the nearest-neighbor carbon results in transfer times of 300 ns between the register qubit and the memory qubit, with an..

(PDF) Nonvolatile nuclear spin memory enables sensor-unlimited.

The nucleus of every element is characterized by a half-integer spin-magnitude () and for an associated magnetic dipole moment which precesses around magnetic fields at the nucleus [7]. These magnetic fields arise from nuclear magnetic moments of nearby atoms/ions. Very recently, nuclear spin memory devices [32], [57], [58] and the indirect hyperfine interaction via electrons between nuclear spin qubits in semiconductor-based quantum computer proposals [33..

Nonvolatile nuclear spin memory enables sensor-unlimited.

. 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.

Proposals of nuclear spin quantum memory in group IV.

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 develop a driven, dissipative protocol to polarize the nuclear spin, based on a rigorous theoretical model of the defect. 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.

The combined sensor-memory spin system. a Schematic representation of the sensor-memory pair comprising the electron and ¹⁴N nuclear spin of an NV center in diamond. Memory in phosphorous-doped silicon, which can be read out electrically and has a lifetime exceeding 100 seconds. The electronic spin infor mation 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.

Solid-state quantum memory using the 31P nuclear spin.

Finally, we explored the coherence properties of the nuclear spin quantum memory. In contrast to the electron spin, which dephases on a time scale T 2e *∼1 μs for this NV center, the nuclear spin free precession signal persisted out to ∼0.5 ms (T 2n * = 495 ± 30 μs in Fig. 4A). Characteristic collapses and revivals in the data correspond.

Optimization of optical spin readout of the nitrogen-vacancy.

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 ). 2. The neural qubit—phosphorus nuclear-spin The nucleus of every element is characterized by a half-integer spin-magnitude (I = 0, 1 2,1 ···) and for I 6= 0 an associated magnetic dipole moment which precesses around magnetic fields at the nucleus [7]. These magnetic fields arise from nuclear magnetic moments of nearby atoms/ions. Nuclei.

Computer Spin Memory: Physicists Read Data Stored in Atomic.

Our approach is to correlate the electronic-spin logic qubit with nearby nuclear spins (), which are relatively unperturbed by the optical readout, before the measurement process ().Specifically, we used one or more 13 C nuclei (with nuclear spin I = 1/2) nuclear spins in the diamond lattice, coupled to the NV electronic spin via a hyperfine interaction, as memory ancillae qubits.

Achieving control of phase memory relaxation times (Tm) in metal ions is an important goal of molecular spintronics. Herein we provide the first evidence that nuclear-spin patterning in the ligand shell is an important handle to modulate Tm in metal ions. We synthesized and studied a series of five V(iv) com. 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.

Sensitive spin seeks single magnon | Nature Physics.

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..
