In this paper, researchers propose a scheme for scalable and robust quantum computing on two-dimensional arrays of qubits with fixed longitudinal coupling. This opens the possibility for bypassing the device complexity associated with tunable couplers […]
Researchers have demonstrated an architecture that can enable high fidelity and scalable communication between superconducting quantum processors. Their technique can generate and route photons, which carry quantum information, in a user-specified direction. This method could […]
A versatile magnetometer must deliver a readable response when exposed to target fields in a wide range of parameters. Researchers have experimentally demonstrated that the combination of 171Yb+ atomic sensors with adequately trained neural networks enables […]
Optically levitated nanoparticles emerged as an interesting platform for probing fundamental physics. Quantum control of their motion (including potential shaping) predisposes them for emulating various physical systems and studying quantum phenomena with massive objects. Extending […]
Spin systems are an attractive candidate for quantum-enhanced metrology. Scientists have developed a variational method to generate metrological states in small dipolar-interacting spin ensembles with limited qubit control. For both regular and disordered spatial spin […]
Much of modern electronic and computing technology is based on one idea: add chemical impurities, or defects, to semiconductors to change their ability to conduct electricity. These altered materials are then combined in different ways […]
Two seemingly different areas of physics are related in subtle ways: Quantum theory and thermodynamics. How can the laws of thermodynamics arise from the laws of quantum physics? This question has now been pursued with […]
Quantum dots are normally made in industrial settings with high temperatures and toxic, expensive solvents — a process that is neither economical nor environmentally friendly. But researchers have now pulled off the process at the […]
