Experimental Scattershot Boson Sampling
Marco Bentivegna, Nicolò Spagnolo, Chiara Vitelli +10
Boson Sampling is a computational task strongly believed to be hard for classical computers, but efficiently solvable by orchestrated bosonic interference in a specialised quantum…
Mutually unbiased bases as minimal Clifford covariant 2-designs
Huangjun Zhu
Mutually unbiased bases (MUB) are interesting for various reasons. The most attractive example of (a complete set of) MUB is the one constructed by Ivanović as well as Wootters and…
Verifying the quantumness of a channel with an untrusted device
Matthew F. Pusey
Suppose one wants to certify that a quantum channel is not entanglement-breaking. I consider all four combinations of trusted and untrusted devices at the input and output of the c…
(1+1)D Calculation provides evidence that quantum entanglement survives a firewall
Eduardo Martin-Martinez, Jorma Louko
We analyze how pre-existing entanglement between two Unruh-DeWitt particle detectors evolves when one of the detectors falls through a Rindler firewall in (1+1)-dimensional Minkows…
Violation of the strong Huygen's principle and timelike signals from the early Universe
Ana Blasco, Luis J. Garay, Mercedes Martin-Benito +1
We analyze the implications of the violations of the strong Huygens principle in the transmission of information from the early universe to the current era via massless fields. We…
Hyperfine spin qubits in irradiated malonic acid: heat-bath algorithmic cooling
Daniel K. Park, Guanru Feng, Robabeh Rahimi +7
The ability to perform quantum error correction is a significant hurdle for scalable quantum information processing. A key requirement for multiple-round quantum error correction i…
