How to Measure the Quantum Measure
Álvaro Mozota Frauca, Rafael Dolnick Sorkin
The histories-based framework of Quantum Measure Theory assigns a generalized probability or measure to every (suitably regular) set of histories. Even though can…
Parasitic Photon-Pair Suppression via Photonic Stop-Band Engineering
L. G. Helt, Agata M. Branczyk, Marco Liscidini +1
We calculate that an appropriate modification of the field associated with only one of the photons of a photon pair can suppress generation of the pair entirely. From this general…
Diagonal gates in the Clifford hierarchy
Shawn X. Cui, Daniel Gottesman, Anirudh Krishna
The Clifford hierarchy is a set of gates that appears in the theory of fault-tolerant quantum computation, but its precise structure remains elusive. We give a complete characteriz…
Compilation of selective pulse network on liquid-state nuclear magnetic resonance system
Jun Li, Jiangyu Cui, Raymond Laflamme +1
In creating a large-scale quantum information processor, the ability to construct control pulses for implementing an arbitrary quantum circuit in a scalable manner is an important…
Information carrying capacity of a cosmological constant
Petar Simidzija, Eduardo Martin-Martinez
We analyze the exchange of information in different cosmological backgrounds when sender and receiver are timelike separated and communicate through massless fields (without the ex…
Experimentally superposing two pure states with partial prior knowledge
Keren Li, Guofei Long, Hemant Katiyar +4
Superposition, arguably the most fundamental property of quantum mechanics, lies at the heart of quantum information science. However, how to create the superposition of any two un…
