Harvard scientists have developed a groundbreaking photon router that creates an optical interface between light signals and superconducting microwave qubits, potentially solving a major quantum computing challenge by enabling different quantum systems to communicate efficiently without bulky wires, thus bringing distributed, fiber-optic-based quantum computers closer to reality.
Researchers have achieved a major quantum computing breakthrough by using a 56-qubit quantum computer to generate certifiably random numbers verified by classical supercomputers, marking a shift from theoretical quantum advantage to practical application with significant implications for cryptography, security, and fairness.
Princeton physicists accidentally discovered and directly visualized Hofstadter’s butterfly—a theoretical fractal pattern of electron energy levels predicted in 1976—using scanning tunneling microscopy on twisted bilayer graphene, revealing not only the long-sought fractal energy spectrum but also new quantum phenomena driven by electron interactions beyond Hofstadter’s original calculations.
D-Wave Quantum Inc. has achieved the world’s first demonstration of quantum computational supremacy on a useful real-world problem, using their Advantage2 prototype quantum annealer to perform complex magnetic materials simulations in minutes that would take a classical supercomputer nearly one million years and consume more than the world’s annual electricity.
Researchers at China’s USTC have developed Zuchongzhi-3, a groundbreaking 105-qubit quantum computer that processes calculations 10^15 times faster than the most powerful supercomputers and one million times faster than Google’s latest quantum systems, marking a significant advancement in quantum supremacy.
