The “spooky action at a distance” that once unnerved Einstein may be on its way to being as pedestrian as the gyroscopes that currently measure acceleration in smartphones. Click to rate this post! [Total: 0 […]
Quantum 7, 986 (2023). https://doi.org/10.22331/q-2023-04-20-986 This work overviews the single-particle two-way communication protocol recently introduced by del Santo and Dakić (dSD), and analyses it using the process matrix formalism. We give a detailed account of […]
Quantum theory, which was formulated in the first three decades of the twentieth century, describes a wide array of phenomena at the molecular, atomic and subatomic scales. Among its many technological applications, three have become […]
In the world of computing, we typically think of information as being stored as ones and zeros—also known as binary encoding. However, in our daily life we use ten digits to represent all possible numbers. […]
Insider Brief The Polytechnic University of Madrid will participate in Madrid Quantum, a quantum communications project based in Madrid. This project will build the Madrid Quantum Communications Infrastructure (MadQCI), a quantum cybersecurity network that will […]
As an undergraduate at the University of Chile, Bernardo Subercaseaux took a dim view of using computers to do math. It seemed antithetical to real intellectual discovery. “There’s some instinct or gut reaction against using […]
Quantum 7, 985 (2023). https://doi.org/10.22331/q-2023-04-20-985 We introduce a methodology for generating random multi-qubit stabilizer codes based on solving a constraint satisfaction problem (CSP) on random bipartite graphs. This framework allows us to enforce stabilizer commutation, […]
Quantum 7, 984 (2023). https://doi.org/10.22331/q-2023-04-20-984 We develop a method to synthesize a class of entangling multi-qubit gates for a quantum computing platform with fixed Ising-type interaction with all-to-all connectivity. The only requirement on the flexibility […]
There are high expectations that quantum computers may deliver revolutionary new possibilities for simulating chemical processes. This could have a major impact on everything from the development of new pharmaceuticals to new materials. Researchers have […]
Quantum 7, 983 (2023). https://doi.org/10.22331/q-2023-04-20-983 For a random set $mathcal{S} subset U(d)$ of quantum gates we provide bounds on the probability that $mathcal{S}$ forms a $delta$-approximate $t$-design. In particular we have found that for $mathcal{S}$ […]
