• Abstract: We present a scheme for quantum randomness certification based on quantum steering. The protocol is one-sided device independent, providing high security, but requires only states and measurements that are simple to realise on quantum optics platforms - entangled squeezed vacuum states and homodyne detection. This ease of implementation is demonstrated by certifying randomness in existing experimental data and implies that giga-hertz random bit rates should be attainable with current technology. Furthermore, the steering-based setting represents the closest to full device independence that can be achieved using purely Gaussian states and measurements.

  We provide a construction of a family of steering inequalities tailored to large classes of $d$-outcomes projective measurements. We prove that the maximal quantum violation of those inequalities can be used for certification of those measurements and the maximally entangled state of two qudits.

• Efficient and Device-Independent Active Quantum State Certification [0.0]
  Entangled quantum states are essential ingredients for many quantum technologies, but they must be validated before they are used. Most existing approaches are based on preparing an ensemble of nominally identical and independent (IID) quantum states, and then measuring each copy of the ensemble. We experimentally implement quantum state certification (QSC), which measures only a subset of the ensemble, certifying the fidelity of the remaining states.

  Quantum secure direct communication (QSDC) uses the quantum channel to transmit information reliably and securely. In order to eliminate the security loopholes resulting from practical detectors, the measurement-device-independent (MDI) QSDC protocol has been proposed. We propose a single-photon-memory MDI QSDC protocol (SPMQC) for dispensing with high-performance quantum memory.

• Quantum randomness certification with untrusted measurements and few probe states [0.0]
  We present a scheme for quantum random-number generation from an untrusted measurement device and a trusted source. No assumptions about noise or imperfections in the measurement are required, and the scheme is simple to implement with existing technology. We show that randomness can be certified in the presence of both Gaussian additive noise and non-Gaussian imperfections.

We develop a systematic approach to device-independent verification of quantum states free of IID assumptions in the finite copy regime. We show that device-independent verification can be performed with optimal sample efficiency.

  A single entangled two-qubit pure state can be used to produce arbitrary amounts of certified randomness. Motivated by these difficulties in the device-independent setting, we consider the scenario of one-sided device independence. We show how certain aspects of previous work can be adapted to this scenario and provide theoretical bounds on the amount of randomness which can be certified.

• Noisy pre-processing facilitating a photonic realisation of device-independent quantum key distribution [0.0]
  Device-independent quantum key distribution provides security even when the equipment used to communicate over the quantum channel is largely uncharacterized. A central obstacle in photonic implementations is that the global detection efficiency must be above a certain threshold. We here propose a method to significantly relax this threshold, while maintaining provable device-independent security.
