Quantum Self-Authenticating Timing Signals is a method that employs the methods of quantum key distribution (QKD) to generate encrypted timing signals from two or more timing beacons. The beacons broadcast timing signals that are nonsensical when taken individually, but that result in valid timing signals when combined appropriately at the receiver. The timing signals can
This invention relates sensors and more specifically to an improved interferometer with twice the sensitivity of conventional nonlinear interferometers with fewer components reducing the cost and complexity. Our design does not require active stabilization. It can be configured for wide bandwidth operation with multiple lasers for sensing many analytes simultaneously and independently. This design can
Memory design is considered to be a major bottleneck for exascale computing. The main goal in memory design is reducing access time and access power. In this invention we present a design of cryogenic memory circuit and demonstrate principles of operation of the proposed circuit by implementing mathematical and computational models. In the proposed design,
The invention relates to quantum communication and more specifically to the development of a deterministic source emitting a single photon of a given frequency and polarization on demand. We solve this fundamental problem with a deterministic single-photon source using a nondeterministic photon-pair source. Like previous attempts, our approach multiplexes many probabilistic sources and uses detection
The invention relates to random number generators and more specifically to a random number generation scheme based on measuring the quadrature fluctuations of a single mode thermal state with an optical homodyne detector. This scheme can be implemented with low-cost, off-the-shelf components, and can generate true randomness at a very high speed. The simple and
This invention generates photon shot noise in a compact balanced photodetection scheme as part of a high bit rate continuous variable quantum random number generator.
We invented a new type of nonlinear interferometer improving upon sensitivity of conventional nonlinear interferometers with fewer components reducing the cost and complexity. This approach has better sensitivity for the same sensing power used in conventional interferometers. Our design does not require active stabilization. It has wide bandwidth operation. It is tolerant to wide temperature
We propose a novel CV QKD scheme using a broadband thermal source. This scheme gets rid of both the random number generator and optical modulator, thus greatly simplifies the implementation of CV QKD and makes it more practical.
Adiabatic quantum computers like the D-Wave 2000Q quantum computer can potentially solve the QUBO problem, which is an NP-Hard problem. Solving the QUBO problem literally means solving virtually any NP-Hard problem like the Traveling Salesman Problem (TSP), Airline Scheduling Problem, Protein Folding Problem, Genotype Imputation Problem etc., thereby enabling significant scientific progress, and potentially saving
We propose a plug-and-play system for QKD in parallel over many channels in a single optical fiber, using frequency-based encoding, which is intrinsically stable and naturally matched to classical optical communications.
