Author(s): Koki Shinada and Naoto NagaosaThe quantum geometric tensor (QGT) provides nontrivial bounds among physical quantities, as exemplified by the metric curvature inequality. How far can this idea be generalized, and what other observables obey such quantum-geometric constraints? The authors show here that generalized QGTs yield new inequalities among all linear responses, the Drude weight, and the orbital magnetization. They further find that this Drude orbital magnetization inequality approaches equality as bands become flatter, which is nearly satisfied in the experimentally observed orbital magnetization of twisted bilayer graphene.

Researchers from Google Quantum AI report that their quantum processor, Willow, ran an algorithm for a quantum computer that solved a complex physics problem thousands of times faster than the world's most powerful classical supercomputers. If verified, this would be one of the first demonstrations of practical quantum advantage, in which a quantum computer solves a real-world problem faster and more accurately than a classical computer.

Quantum key distribution (QKD) harnesses the power of quantum mechanics to securely transmit confidential information. When an outside source eavesdrops on a QKD transmission, the quantum states are affected. This dependably alerts the receiver and sender that the transmission is no longer secure.

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) with quantum mechanics and many attempts at explaining a "quantum gravity," scientists are still coming up short. Still, some believe we are getting closer to determining whether these two theories can be combined or whether they are truly incompatible.

With the rise of quantum computers, the security of our existing communication systems is at risk. Quantum computers will be able to break many of the encryption methods used in current communication systems. To counter this, scientists are developing quantum communication systems, which utilize quantum mechanics to offer stronger security. A crucial building block of these systems is a single-photon source. For quantum communication systems to work, it is essential that single photons are injected into optical fibers with extremely low loss. In conventional systems, single-photon emitters, such as quantum dots and rare-earth element ions, are placed outside the fiber. These photons then must be guided to enter the fiber. However,...

Author(s): Arman Sauliere, Beatrice Magni, Guglielmo Lami, Xhek Turkeshi, and Jacopo De NardisThe authors uncover here a universal functional form governing anticoncentration, which quantifies how broadly the output probabilities of a random quantum circuit are distributed, across architectures, depths, and even finite system sizes. Using analytical models and extensive simulations, they show that these distributions are characterized by just two parameters. Their results highlight finite-size and finite-depth effects and provide a practical framework for benchmarking quantum devices, enabling validation of much larger systems than previously possible.
