Abstract: Techniques for providing an optimized quantum computing model are described. In operation, a gate teleportation circuit for a predetermined number of qubits is obtained. The gate teleportation circuit is then segmented into multiple sub-circuits. A gate teleportation operation is then performed on each of the multiple sub-circuits wherein the gate teleportation operation on each of the multiple sub-circuits is performed based on the at least one qubit of a given sub-circuit and an output of a gate teleportation operation performed on a sub-circuit which is previous to the given sub-circuit. An output of the gate teleportation operation performed on the last sub-circuit from the multiple sub-circuits is then measured.

Abstract: Techniques for quantum data storage are described. A method for quantum data storage in ultra long storage assisted quantum memory includes obtaining quantum data from an input quantum channel to be stored in a memory unit, storing, intermediately, the quantum data in a first medium of the memory unit for a first pre-determined amount of time, reabsorbing quantum data emitted from the first medium after the first pre-determined amount of time by at least one multiple dot heterostructure of the memory unit, where the at least one multiple dot heterostructure comprises a potential well for storing the quantum data, storing quantum data in the at least one multiple dot heterostructure for a second predetermined amount of time, and performing a controlled tunneling of the quantum data stored in the at least one multiple dot heterostructure.

Abstract: Approaches for implementing MDI-QSDC with user authentication are described. A sending system may prepare a first set of entangled qubit bit pairs, wherein the qubit bit pairs are prepared randomly. The first set of entangled qubit bit pairs may be separated into a first particle sequence and a second particle sequence. Thereafter, a second set of entangled qubit bit pairs based on an identifier corresponding to the quantum communication system may be prepared. A first set of decoy photons may be interleaved into the first particle sequence and a first single photon sequence, and a second set of decoy photons into the second particle sequence and the second single photon sequence to provide a first and a second sequence of single qubits. The second sequence is communicated to an untrusted third party for measurement based on which communication may be continued.

Abstract: Techniques for providing a simulator for quantum computing systems are described. In operation, a gate teleportation circuit for a predetermined number of qubits is obtained, where the gate teleportation circuit is complaint with Measurement Based Quantum Computing model of quantum computing. Thereafter, segmentation of the gate teleportation circuit into multiple sub-circuits is simulated. A gate teleportation operation is then simulated on each of the multiple sub-circuits, where the gate teleportation operation on each of the multiple sub-circuits is simulated based on the at least one qubit of a given sub-circuit and an output of a gate teleportation operation performed on a sub-circuit which is previous to the given sub-circuit. An output of the gate teleportation operation simulated on the last sub-circuit from the multiple sub-circuits is then measured.
