Suppose you are trying to transmit a message. Convert each character into bits, and each bit into a signal. Then send it, over copper or fiber or air. Try as you might to be as […]
Quantum 5, 587 (2021). https://doi.org/10.22331/q-2021-11-24-587 We present two new results about exact learning by quantum computers. First, we show how to exactly learn a $k$-Fourier-sparse $n$-bit Boolean function from $O(k^{1.5}(log k)^2)$ uniform quantum examples for […]
Researchers from Basel and Bochum have succeeded in addressing an apparently unattainable energy transition in an artificial atom using laser light. Making use of the so-called radiative Auger process, they were the first team to […]
Kicking the quantum cybersecurity can down the road my be a potentially devastating delay tactic, a team of cybersecurity experts and quantum information scientists warn. While current quantum computers may not be a threat to […]
QuTech, a Dutch organization that is a collaboration between the TU Delft and TNO, has introduced a web site where users can simulate various aspects of a quantum internet. At this time, the simulations are […]
In recent years, many physicists worldwide have been investigating the behavior of hybrid nanostructures. These are systems that are typically made up of two or more materials. Special attention in this class of structures is […]
Quantum 5, 586 (2021). https://doi.org/10.22331/q-2021-11-23-586 We present a new tensor network algorithm for calculating the partition function of interacting quantum field theories in 2 dimensions. It is based on the Tensor Renormalization Group (TRG) protocol, […]
23 November 2021, Toronto, ON – Matching the explosive growth of the quantum industry, the quantum technology’s leading media and data provider announced today that it will formally launch its market intelligence platform and rebrand […]
An elegant ballet of proteins enables modern cells to replicate themselves. During cell division, structural proteins and enzymes coordinate the duplication of DNA, the division of a cell’s cytoplasmic contents, and the cinching of the […]
