A new quantum algorithm developed by University of Georgia statisticians addresses one of the most complex challenges in single-cell analysis, signaling significant impact in both the fields of computational biology and quantum computing.

The study, “Bisection Grover’s Search Algorithm and Its Application in Analyzing CITE-seq Data,” was published in the Journal of the American Statistical Association on Sept. 20.

While traditional approaches struggle to handle the immense amount of data generated from measuring both RNA and in individual cells, the new enables analysis of data from a single-cell technology known as CITE-seq. It allows for selection of the most important markers from billions of possible combinations—a task that would be formidable using classical methods.

This article introduces the “Scaling Entropy-Area Thermodynamics” (SEAT), a unified framework claiming that all gravitational systems’ entropy scales with their surface, rather their volume, allowing gravity to be explained as an emergent phenomenon. This approach reveals how entropy, information, spacetime geometry and quantum mechanics are intrinsically linked fromnotions such as von Neumann entropy, Bekenstein bound and Ryu-Takayanagi conjecture. With the help of new entropy formulations involving surface gravity, SEAT illustrates how gravitational entropy explains gravitational systems from structured information at the boundary surface.

Over the past few years, some researchers have been working on alternative energy storage systems that leverage the principles of quantum mechanics. These systems, known as quantum batteries, could be more efficient and compact than conventional battery technologies, while also achieving faster charging times.

In a recent paper published in Physical Review Letters, a research group at University of Genova introduced a new spin quantum battery, a battery that leverages the spin degrees of freedom of particles to store and release energy. This battery is charged in a unique and advantageous way, without the need for an external field.

“Quantum many-body theory and non-equilibrium physics are traditional topics in the quantum condensed matter theory group led by Maura Sassetti at University of Genova,” Dario Ferraro, senior author of the paper, told Phys.org.
