Artificial neural networks are the heart of machine learning algorithms and artificial intelligence. Historically, the simplest implementation of an artificial neuron traces back to the classical Rosenblatt’s “perceptron”, but its long term practical applications may be hindered by the fast scaling up of computational complexity, especially relevant for the training of multilayered perceptron networks. Here we introduce a quantum information-based algorithm implementing the quantum computer version of a binary-valued perceptron, which shows exponential advantage in storage resources over alternative realizations. We experimentally test a few qubits version of this model on an actual small-scale quantum processor, which gives answers consistent with the expected results. We show that this quantum model of a perceptron can be trained in a hybrid quantum-classical scheme employing a modified version of the perceptron update rule and used as an elementary nonlinear classifier of simple patterns, as a first step towards practical quantum neural networks efficiently implemented on near-term quantum processing hardware.

An electron spin resonance spectrometer using an artificial atom (a superconducting flux qubit) is realized, featuring both high sensitivity (400 spins/√Hz) and high spatial resolution (0.05 pL).

A few days back we talked about a joint NASA and ESA study that was being conducted in Germany looking at long term effects of weightlessness on astronauts and how artificial gravity might help them. More details have surfaced about that study, and it pays very well for doing nothing but laying in bed. The study pays participants $19,000 (16,500 euro) and is known as AGBRESA study 2019.

The first Women in Science Open House aims to inspire young women in the STEM field.

Michelle Cash, program coordinator at the Sandy Creek Nature Center, the event has been something she has wanted to do for a long time. After speaking with an intern at the nature center, they realized now is the perfect time because of recent social movements and the increase of women in political power.

“I think this is a good time to recognize and start to make people aware that there’s women out there doing really good stuff for science and has been doing stuff for science for a long, long time,” Cash said.

Lanthanum, diamond crushers and advanced computer models are changing the hunt for this extreme quantum mechanical effect.

Regions Financial Corporation has barred its customers from purchasing cryptocurrencies such as bitcoin.

The US-based bank and financial service clarified in its 2018 bank deposit agreement that it reserved the right to “return or decline to pay” for items related to “decentralized, non-fiat virtual currencies, cryptocurrency or another digital currency or money that relies on distributed ledger or blockchain.”

But the technology could also, theoretically, be used to develop placid super-soldiers.

The hunt for gravitational waves is back on. After a series of upgrades, the National Science Foundation’s Laser Interferometer Gravitational-Wave Observatory (LIGO) will resume its search for ripples in space and time on Monday, April 1.

LIGO is famous for making the first direct detection of gravitational waves in 2015, for which the observatory’s founders were awarded the Nobel Prize. The observatory was able to detect gravity waves generated by two colliding black holes which were located 1.3 billion light-years away from Earth, and since then has observed nine more black hole mergers and one collision of two neutron stars.

Gravitational waves are ripples in the fabric of spacetime, caused by massive bodies which bend it like a bowling ball placed on a rubber sheet. They were predicted by Einstein as part of his general theory of relativity in 1916, but it took nearly a century for physicists to observe them because the effects are so small. Since these waves have been detected, they can be used to investigate cosmic objects as an alternative to light-based telescopes.
