摘要： 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 radiation of higher power than the first optical radiation to decouple the electronic spin from the nuclear spin thereby increasing coherence time of the nuclear spin; a first pulse source configured to generate radio frequency (RF) excitation pulse sequences to manipulate the nuclear spin and to dynamically decouple the nuclear spin from one or more spin impurities in the solid state lattice so as to further increase the coherence time of the nuclear spin; a second pulse source configured to generate microwave excitation pulse sequences to manipulate the electronic spin causing a change in intensity of the output optical radiation correlated with the electronic spin and with the nuclear spin via the coupling between the electronic spin and the nuclear spin; and a detector configured to detect the output optical radiation correlated with the electronic spin and the nuclear spin so as to detect a nuclear spin state of the nuclear spin.

摘要： A quantum ticket is defined by a unique serial number; and a set of qubits, each qubit encoding quantum information. The serial number and the set of qubits are distributed only among one or more trusted verifiers who require a tolerance fidelity Ftol in order to authenticate the token, where Ftol represents a minimum percentage of correct outcomes during authentication of the serial number and the set of qubits. The experimental fidelity Fexp for the quantum token is greater than the Ft0i set by the verifiers, so that an honest user of the quantum ticket who achieves Fexp is exponentially likely to be successfully authenticated when seeking authentication by any of the trusted verifiers. The forging fidelity Fforg for the quantum token is less than Ft0i, so that a dishonest user who achieves Fforg and attempts forgery of the quantum ticket is exponentially likely to fail to obtain authentication for his forged ticket.

摘要： A method is disclosed for increasing the sensitivity of a solid state electronic spin based magnetometer that makes use of individual electronic spins or ensembles of electronic spins in a solid-state lattice, for example NV centers in a diamond lattice. The electronic spins may be configured to undergo a Zeeman shift in energy level when photons of light are applied to the electronic spins followed by pulses of an RF field that is substantially transverse to the magnetic field being detected. The method may include coherently controlling the electronic spins by applying to the electronic spins a sequence of RF pulses that dynamically decouple the electronic spins from mutual spin-spin interactions and from interactions with the lattice. The sequence of RF pulses may be a Hahn spin-echo sequence, a Can Purcell Meiboom Gill sequence, or a MREV8 pulse sequence, by way of example.

摘要： A quantum information processor (QIP) may include a plurality of quantum registers, each quantum register containing at least one nuclear spin and at least one localized electronic spin. At least some of the quantum registers may be coherently coupled to each other by a dark spin chain that includes a series of optically unaddressable spins. Each quantum register may be optically addressable, so that quantum information can be initialized and read out optically from each register, and moved from one register to another through the dark spin chain, though an adiabatic sequential swap or through free-fermion state transfer. A scalable architecture for the QIP may include an array of super-plaquettes, each super-plaquette including a lattice of individually optically addressable plaquettes coupled to each other through dark spin chains, and separately controllable by confined microwave fields so as to permit parallel operations.

摘要： Illustrative embodiments include a method, system, and computer program product for estimating boot-time memory requirement of a data processing system. A data processing system identifies, using system configuration information associated with the data processing system, a set of components needed for booting up the data processing system. The data processing system determines a dependency of a component identified in the set of components, the component including a memory estimator program. The data processing system determines an ancestry of the component identified in the set of components. The data processing system receives, using the memory estimator program of the component, a boot-time memory requirement of the component. The data processing system calculates a total boot-time memory requirement. The data processing system determines whether an amount of real memory of the data processing system satisfies the total boot-time memory requirement.

摘要： Embodiments of MIMO symbol decoders and methods for decoding spatially multiplexed symbols using combined linear equalization decoding and maximum likelihood decoding are generally described herein. In some embodiments, one group of symbols (y) received through two or more spatial channels is decoded using a linear equalization decoding technique and another group of symbols is decoded using a maximum likelihood decoding (MLD) technique to generate a soft-bit output. The symbols may be grouped for either linear equalization decoding or MLD based on channel orthogonality or signal-to-interference and noise ratios (SINRs).
