Researchers present a #quantummachinelearning advantage of families of constant depth local quantum circuits over reasonably constrained log-log-depth classical circuits.
Quantum…
One of the core challenges of research in quantum computing is concerned with the question whether quantum advantages can be found for near-term quantum circuits that have implications for practical applications. Motivated by this mindset, in this work, we prove an unconditional quantum advantage in the probably approximately correct (PAC) distribution learning framework with shallow quantum circuit hypotheses. We identify a meaningful generative distribution learning problem where constant-depth quantum circuits using one and two qubit gates (QNC^0) are superior compared to constant-depth bounded fan-in classical circuits (NC^0) as a choice for hypothesis classes. We hence prove a PAC distribution learning separation for shallow quantum circuits over shallow classical circuits. We do so by building on recent results by Bene Watts and Parham on unconditional quantum advantages for sampling tasks with shallow circuits, which we technically uplift to a hyperplane learning problem, identifying non-local correlations as the origin of the quantum advantage.

A new study describes an exciting discovery that changes the way we understand human bitter taste receptors. The research has revealed a hidden “pocket” inside one of the body’s bitter taste receptors, called TAS2R14.
This breakthrough could help not only understand how our tongue senses bitterness but also investigate the physiological roles of bitter taste receptors that are expressed extraorally. The work is published in Nature Communications, and was led by Prof. Masha Niv from the Hebrew University of Jerusalem, Dr. Moran Shalev-Benami from the Weizmann Institute, and Dr. Dorothee Weikert from FAU Erlangen.
There are many chemically different molecules that trigger bitter taste sensations, and the body uses a family of 25 receptors to detect them. Interestingly, many drugs also activate this bitter taste system.

Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission.
New research published in Current Biology has found that cyanobacteria use variations in the amplitude (strength) of a pulse to convey information in single cells. The finding sheds light on how biological rhythms work together to regulate cellular processes.
In AM (amplitude modulation) radio, a wave with constant strength and frequency—called a carrier wave—is generated from the oscillation of an electric current. The audio signal, which contains the information (such as music or speech) to transmit, is superimposed onto the carrier wave. This is done by varying the amplitude of the carrier wave in accordance with the frequency of the audio signal.
Particle physicists have been looking for so-called “sterile neutrinos” for a few decades now. They are a hypothesized particle that would have a tiny mass like the three known neutrinos but would not interact by the weak force or any other Standard Model force, only through gravitational interactions.
Its existence—or their existence—would solve some anomalies seen in neutrino experiments, help answer questions beyond the Standard Model of particle physics, and, if massive enough, could explain cold dark matter or warm dark matter.
But sterile neutrinos have not been seen in any particle experiments, despite many attempts. Now an experiment by the IceCube Collaboration has used 10.7 years of data from their detector near the Amundsen-Scott South Pole Station to lower the probability that at least one sterile neutrino does not exist. Their paper appears in Physical Review Letters.
