Approximate exchange-only entangling gates for the three-spin- decoherence-free subsystem
James. R. van Meter, Emanuel Knill
The three-spin- decoherence-free subsystem defines a logical qubit protected from collective noise and supports exchange-only universal gates. Such logical qubits are well-sui…
Experimental Low-Latency Device-Independent Quantum Randomness
Yanbao Zhang, Lynden K. Shalm, Joshua C. Bienfang +10
Applications of randomness such as private key generation and public randomness beacons require small blocks of certified random bits on demand. Device-independent quantum random n…
Certifying Quantum Randomness by Probability Estimation
Yanbao Zhang, Emanuel Knill, Peter Bierhorst
We introduce probability estimation, a broadly applicable framework to certify randomness in a finite sequence of measurement results without assuming that these results are indepe…
Quantum Probability Estimation for Randomness with Quantum Side Information
Emanuel Knill, Yanbao Zhang, Honghao Fu
We develop a quantum version of the probability estimation framework [arXiv:1709.06159] for randomness generation with quantum side information. We show that most of the properties…
Quantum Process Fidelity Bounds from Sets of Input States
Karl Mayer, Emanuel Knill
We investigate the problem of bounding the quantum process fidelity given bounds on the fidelities between target states and the action of a process on a set of pure input states.…
Challenging local realism with human choices
The BIG Bell Test Collaboration, C. Abellán, A. Acín +105
A Bell test is a randomized trial that compares experimental observations against the philosophical worldview of local realism. A Bell test requires spatially distributed entanglem…
