Bandwidth and energy are two fundamental resources needed to exchange information. In digital communication, information is encoded in a finite set of physical states known as symbols. In optics, modulated laser pulses are often used […]
A team of experimental physicists, at the University of Innsbruck, Austria, has implemented a universal set of computational operations on fault-tolerant quantum bits for the first time, demonstrating how an algorithm can be programmed on […]
Researchers at the Advanced Quantum Testbed (AQT) at Lawrence Berkeley National Laboratory (Berkeley Lab) conducted the first experimental demonstration of a three-qubit high-fidelity iToffoli native gate in a superconducting quantum information processor and in a […]
Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the University of Chicago performed quantum simulations of spin defects, which are specific impurities in materials that could offer a promising basis for […]
A laser pulse that sidesteps the inherent symmetry of light waves could manipulate quantum information, potentially bringing us closer to room temperature quantum computing. While laser pulses can be used to manipulate the energy states […]
Scientists have been relentlessly working on understanding the fundamental mechanisms at the base of high-temperature superconductivity with the ultimate goal to design and engineer new quantum materials superconducting close to room temperature. A team of […]
A team of scientists at IBM Quantum used laser annealing to selectively tune transmon qubits into the desired frequency patterns. Superconducting quantum processors with more than 50 qubits are currently actively available and these fixed […]
Researchers at University of Central Florida are developing new photonic materials that could one day help enable low power, ultra-fast, light-based computing. The unique materials, known as topological insulators, are like wires that have been […]
At first glance, a system consisting of 51 ions may appear simple. But even if these charged atoms can only assume two different states, there will be more than two quadrillion (1015) different configurations which the system can […]
Researchers have introduced an inductive n-qubit pure-state estimation method based on projective measurements on mn + 1 separable bases or m entangled bases plus the computational basis, with m ≥ 2. The method exhibits a favorable scaling in the number of qubits compared to […]
