• Abstract: We demonstrate a die-level balanced homodyne detector with a high quantum-to-classical noise clearance of 19.1dB over 3GHz bandwidth. We evaluate this receiver as a high-quality entropy source for random number generation at >10Gb/s and prove the functional integration of a classical 10Gb/s duobinary communication channel.

• Quantum Random Number Generation Based on Phase Reconstruction [1.1085288227234302]
  Quantum random number generator (QRNG) utilizes the intrinsic randomness of quantum systems to generate genuine random numbers. Traditional phase noise QRNGs suffer from a 50% loss of quantum entropy during the randomness extraction process. We propose a phase-reconstruction quantum random number generation scheme, in which the phase noise of a laser is reconstructed by simultaneously measuring the quadratures of the light field.

The fully integrated receiver capability to read out at least 90 qubits positions this design for potential applications in quantum computing.

  We employ a machine learning-enabled approach to quantum state engineering based on evolutionary algorithms. We consider a network of qubits -- encoded in the states of artificial atoms with no direct coupling -- interacting via a common single-mode driven microwave resonator. We observe high quantum fidelities and resilience to noise, despite the algorithm being trained in the ideal noise-free setting.
