  • QUANTUM COMPUTING APPARATUS WITH PHOTONS AND ATOMIC MEMORIES
    Publication number: 20250384319
    Abstract: Systems and methods to perform quantum computing using a Rydberg blockade effect for a photon-photon nonlinear interaction at the single photon level that realizes a controlled-phase (CP) gate between control and target qubits that are encoded in the polarizations of a photon pair. Electromagnetically induced transparency (EIT) is used to write the photonic quantum state into the ground states of an ensemble of atoms. Then a controlled phase shift is induced via combination of Rabi flopping/oscillations and a Rydberg blockade effect. Then EIT transfers the quantum state with the conditional phase shift back from the ensemble of atoms to the photon pair, resulting in a CP gate. Waveplates before and after the ensemble of atoms can convert the CP gate to a CNOT gate. Distributed quantum computing is realized by transporting the photons between spatially separated quantum memories (i.e., ensemble of atoms).

  • Systems and methods for ultra-wideband (UWB) radar detection and tracking of tumors in real-time
    Patent number: 10993619
    Abstract: An ultra-wideband (UWB) radar system for non-invasive, real-time tumor tracking includes an UWB transmitter arranged to transmit radar pulses to penetrate a region of interest of a patient; an UWB receiver arranged to receive radar return pulses after being reflected by tumor tissue in the region of interest of the patient; and an UWB signal processor constructed to communicate with the UWB receiver, wherein the UWB transmitter and the UWB receiver are constructed to be arranged sufficiently far away from the patient so as to avoid interfering with radiation treatment of the tumor.
