Credit: Leon Zaborski – University of Cambridge An international team of scientists has demonstrated a leap in preserving quantum coherence for quantum dot qubits as part of a global push … Read more
Illustration of two slides comprising two entangled quantum light sources. Credit: Peter Luddell In a new breakthrough, researchers at the University of Copenhagen, in collaboration with Ruhr University Bochum, have solved a problem that has been causing quantum researchers headaches for years. Researchers can now control two quantum light sources instead of just one. As … Read more
A team of researchers at Boston College discovered that the photocurrent flows (shown in blue) along the axis of a single crystal of a Weyl semi-metal and flows out (shown in yellow/orange) along the vertical axis, represented here as the result of a new technique the team developed using quantum magnetic field sensors. To visualize … Read more
Three weeks ago, panic gripped some corners of the security world after researchers discovered a hack that finally put cracking the widely used RSA encryption system within reach using quantum computing. Scientists and cryptographers have known for two decades that a method of analysis known as the Shore algorithm makes it theoretically possible for a … Read more
These are the eight articles in a series of articles that explore the birth of quantum physics. Scientists have worldviews. This is not too surprising, given that they are people, and humans have worldviews. You have a way of thinking about politics, religion, science, and the future, and that way of thinking informs how you … Read more
JCN Newswire2023-01-23 TOKYO, Jan. 23, 2023 — (JCN Newswire) — With concerns growing surrounding the potential threat quantum computing poses to existing cryptographic methods, Fujitsu today revealed that it has conducted successful experiments evaluating the widely used RSA cipher(1) for its potential for vulnerability. To crack the code by quantum computers. Fujitsu conducted the experiments … Read more
Cosmologists have spent For decades you’ve struggled to understand why the universe is so amazing. Not only is it smooth and flat as far as we can see, but it’s also expanding at an ever-increasingly slow pace, when naive calculations suggest that – out of the Big Bang – space should have been gravitationally collapsed … Read more
The experimental setup (Fig. 1) used to evaluate co-propagation consisted of a DWDM comb composed of sixty 100 Gb/s DP-QPSK (double polarization quadruple shift switch) channels ranging from 1533.6 to 1557 nm (with 50 GHz spacing) and sent to an Aux input ( Rx) for Alice’s side station.
