Microwave-free nuclear magnetic resonance at molecular.

May 14, 2021 • Physics 14, 73 A small device performs rotational measurements using nuclear spins in a diamond wafer, paving the way for microchip-size gyroscopes. Tom/ Hold that tilt. Like a toy gyroscope, the nuclear spins inside a diamond crystal maintain a stable orientation—which can be used to measure rotations.

Optically addressable universal holonomic quantum gates on.

Here, we demonstrate microwave-driven holonomic quantum gates on an optically selected electron spin in a nitrogen-vacancy centre in diamond. The electron spin is precisely manipulated with global. The arrows indicate electron spin resonance (ESR) transitions. (b) ESR spectrum of the spin system recorded at a magnetic field B = 850 G by sweeping the frequency of a microwave field while monitoring the spin-dependent photoluminescence (PL) intensity of the NV defect. Here the nuclear spin mixing parameter is θ ≈ 1.14 rad. The red solid.

Two-Electron-Spin Ratchets as a Platform for Microwave-Free.

A microwave energy emitter ( 108 ) is positioned in a microwave transparent chamber ( 123 ) within a material holding vessel ( 106 ) of a microwave containment vessel ( 122 ). The holding vessel ( 106 ) may be transparent to microwave energy and is further provided with a microwave reflective component outward, on, or beyond an exterior surface ( 121 ) of the wall of the holding vessel ( 106 ).

Nuclear Magnetic Moments. Associated with each nuclear spin is a magnetic moment which is associated with the angular momentum of the nucleus. It is common practice to express these magnetic moments in terms of the nuclear spin in a manner parallel to the treatment of the magnetic moments of electron spin and electron orbital angular momentum.. For the electron spin and orbital cases, the.

Here we study two of these three elements, demonstrating coherent storage and retrieval between electron and (145)Nd nuclear spin states in Nd(3+):YSO. We find nuclear spin coherence times can reach 9 ms at ∼5 K, about 2 orders of magnitude longer than the electron spin coherence, while quantum state and process tomography of the storage or. The treatment of the two-spin Hamiltonian was J. Chem. Phys. 134, 125105 (2011) used to understand microwave-excited electron-nuclear transitions that lead to enhancements of nuclear polarization via the SE.36 Furthermore, calculations with a three-spin Hamiltonian provided an understanding of the generation of nuclear coherences with spin.

However, experiments with single electron and nuclear spins so far only reach into frequency ranges of several 10 GHz, where existing coplanar waveguide structures for microwave (MW) delivery are compatible with single spin readout techniques (e.g., electrical or optical readout).

. Large-scale quantum computers must be built upon quantum bits that are both highly coherent and locally controllable. We demonstrate the quantum control of the electron and the nuclear spin of a single 31 P atom in silicon, using a continuous microwave magnetic field together with nanoscale electrostatic gates. The qubits are tuned into resonance with the microwave field by a local change in. The application of a narrowband, a photomultiplier tube or fluorescent atoms that long coherence times that fulfills most of the re- nuclear spin state-selective microwave (MW) p are shelved in a dark state, which is not a qubit quirements needed to build a quantum computer pulse flips the electron spin into the j−1e 〉 state state).

Ultrafast control of nuclear spins using only microwave.

The ability to optically initialize the electronic spin of the nitrogen-vacancy (NV) center in diamond has long been considered a valuable resource to enhance the polarization of neighboring nuclei, but efficient polarization transfer to spin species outside the diamond crystal has proven challenging. Here we demonstrate variable-magnetic-field, microwave-enabled cross-polarization from the NV. Nuclear spin polarization is detectable by measuring peculiarities of the electron transport in a semiconductor device under a microwave radiation as is in the case of the most recent measurements of this kind. Optical excitation of the charge carriers modifies the polarization of the underlying nuclear spin subsystem, thus creating spatially.

The pulsed plasma jet beam enters the high Q Fabry-Pérot cavity, then a microwave pulse is broadcast onto the jet pulse at the center of the cavity. If the transition lies within the 300 kHz bandwidth of the microwave pulse and cavity mode combination, a macroscopic polarization is induced in the molecular species.

Microwave system for DNP using a YIG (Yttrium Iron Garnet) source and simple microwave antenna for the study of conduction-electron-nuclear spin interactions in quantum well (QW) thin film of GaAs/AlGaAs. Such quantum confined structures have garnered a lot of attention5 for possible spintronics and quantum computing purposes. Our system uses a spin ensemble to couple between microwave photons of a TLR and a microwave cavity (LC circuit) which have different frequencies. Moreover, a mechanical resonator in the capacitor of the microwave cavity leads to an electromechanical interaction between microwave field and the mechanical motion.
