Stephan Sullivan An artist’s representation shows the researchers’ quantum functional groups (bright colored spheres) linked to larger molecules. Main takeaways: Stronger, faster. Quantum computers promise far greater speed and processing power than today’s most advanced supercomputers Quantum quantum. As these next-generation computers relied on the interaction of fragile atomic and subatomic particles, increasing their processing power proved to be a challenge. A chemical solution. Researchers have created a new molecule that has the potential to protect quantum interactions on a larger scale without the need for traditional electrical engineering tools and machines. Quantum computing, although still in its infancy, has the potential to dramatically increase processing power by exploiting the odd behavior of particles at the smallest scales. Several research groups have reported performing calculations that would take thousands of years for traditional supercompu...

Every biological process is highly dependent on temperature. This applies to the very small, the very large, and every scale in between, from molecules to ecosystems and in every environment. A general theory explaining how life depends on temperature is lacking — until recently. In a paper published in the Proceedings of the National Academy of Sciences, researchers led by Jose Ignacio Arroyo, a Santa Fe Institute Postdoctoral Fellow, introduce a simple framework that strictly predicts how temperature affects living things, at all scales. “This is very basic,” says SFI External Professor Pablo Marquet, an ecologist at the Pontifica Universidad Catolica de Chile, in Santiago. Marquet, Ph.D. thesis advisor, is also working on the model. “You can apply this to almost any process that is affected by temperature. We hope this will be an important contribution.” Marquet noted that such a theory could help researchers make accurate predictions in a variety of areas, including biologica...

The Quantum Hall Effect (QH) enables the exploitation of the quantum coherence of electrons for a wide range of applications from metrology to quantum computing. QH interferometry is a handy tool that provides an archetypal platform for achieving interwoven statistics of fractional QH states. However, the phase coherence along the interferometer and the suppression of the Coulomb filling energy are required to observe the fractional statistics. Study: Quantum Hall interferometry in the triangular domain of a marginally twisted bilayer graphene. Image Credit: Neon_dust/Shutterstock.com In an article recently published in the journal nano letter, The QH interferometer is based on a slightly twisted bilayer graphene with a twist angle (θ) of 0.16 degrees. Operation of the device in the QH regime results in unique magneto-thermopower features, including Aharonov–Bohm (AhB) and Fabry–Pérot (FP) oscillations in the magnetic-density field phase, where the Landau level fill factor (ν) is 4...

The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of atomic clocks and quantum sensors, which are atomic systems whose fluctuations can indicate the presence of dark matter, passing gravitational waves, or even phenomena. unexpected new. The main obstacle on the road to better quantum measurements is noise from the classical world, which can easily overwhelm the subtle vibrations of atoms, making any changes to those vibrations extremely difficult to detect. Now, MIT physicists have shown that they can significantly amplify quantum changes in atomic vibrations, by placing particles through two key processes: quantum entanglement and time reversal. Before you start shopping for DeLoreans, no, they haven’t figured out how to turn back time itself. Instead, physicists have manipulated quantum entangled atoms in such a way that the particles...

Washington [US]July 9 (ANI): Researchers have entangled two quantum memories via a 33-kilometer-long fiber-optic connection, a record and an important step towards a quantum internet. A network where data transmission is highly secure against hacking? If physicists succeed, this will one day become a reality with the help of the quantum mechanical phenomenon known as entanglement. For entangled particles, the rule is: If you measure the state of one particle, you automatically know the state of the other. It makes no difference how far the particles are entangled with each other. This is the ideal state for transmitting information over long distances in a way that makes eavesdropping impossible.

University of Chicago physicists have discovered a “quantum flute” that, like the Pied Piper, can force light particles to move together in a way never seen before. Described in two studies published in Physical Review Letters and Nature Physics, the breakthrough could point the way to the realization of quantum memory or new forms of error correction in quantum computers, and to observe quantum phenomena that cannot be seen in nature. Laboratory Association Prof. David Schuster is working on quantum bits – the quantum equivalent of computer bits – that take advantage of the peculiar properties of particles at the atomic and sub-atomic level to do things that would otherwise be impossible. In this experiment, they worked with light particles, known as photons, in the microwave spectrum. Their system consists of long cavities built into a metal block, designed to trap photons at microwave frequencies. Cavities are created by drilling offset holes — like holes i...
