Device-Independent Randomness Amplification
Anatoly Kulikov, Simon Storz, Josua D. Schär +6
Successful realization of Bell tests has settled an 80-year-long debate, proving the existence of correlations which cannot be explained by a local realistic model. Recent experime…
Realization of Constant-Depth Fan-Out with Real-Time Feedforward on a Superconducting Quantum Processor
Yongxin Song, Liberto Beltrán, Ilya Besedin +8
When using unitary gate sequences, the growth in depth of many quantum circuits with output size poses significant obstacles to practical quantum computation. The quantum fan-out o…
Deterministic generation of a 20-qubit two-dimensional photonic cluster state
James O'Sullivan, Kevin Reuer, Aleksandr Grigorev +11
Multidimensional cluster states are a key resource for robust quantum communication, measurement-based quantum computing and quantum metrology. Here, we present a device capable of…
Mitigating Losses of Superconducting Qubits Strongly Coupled to Defect Modes
Dante Colao Zanuz, Quentin Ficheux, Laurent Michaud +16
The dominant contribution to the energy relaxation of state-of-the-art superconducting qubits is often attributed to their coupling to an ensemble of material defects which behave…
