MIT researchers developed a photon-shuttling “interconnect” that can facilitate remote entanglement, a key step toward a practical quantum computer.

Nuclear spins in a crystal can be detected and manipulated through their interactions with the more accessible electron spin of a neighboring crystal defect. This strategy has enabled nanoscale magnetic resonance imaging and other quantum applications. But a long-standing challenge has been to target a specific nuclear spin, while protecting the delicate quantum nature of the electron spin. Important progress on this challenge has now been achieved by two teams at the Delft University of Technology in the Netherlands.

In their ongoing efforts to push the boundaries of quantum possibilities, physicists at WashU have created a new type of “time crystal,” a novel phase of matter that defies common perceptions of motion and time.

Aravind Nagulu, a professor of electrical and computer science, wants to cut qubit costs for AI, cryptography, drug discovery and energy research.

Superconducting circuits are being used at TU Wien and ISTA to create new types of quantum systems that are much easier to control and much more tunable than natural quantum systems like atoms.

Now, in a recently published Nature paper, JILA and NIST Fellow and University of Colorado Boulder Physics Professor Jun Ye and his team, along with collaborators in Mikhail Lukin’s group at Harvard University, used periodic microwave pulses in a process known as Floquet engineering, to tune interactions between ultracold potassium-rubidium molecules in a system appropriate for studying fundamental magnetic systems. Moreover, the researchers observed two-axis twisting dynamics within their system, which can generate entangled states for enhanced quantum sensing in the future.

In a recent paper published in Physical Review Letters, researchers of the Munich Center for Quantum Science and Technology (MCQST) - in collaboration with researchers from Regensburg, Heidelberg and Harvard University - propose a new scheme to emulate doped, bosonic quantum magnets in state-of-the-art cold atom and molecule experiments. Instead of relying on physical tunneling of the mobile dopants, they develop a protocol that utilizes the rich internal structure of atoms and molecules to implement the charge and spin degrees-of-freedom.

QuantrolOx’s Quantum EDGE qubit automation software has set a new benchmark for speed and ease of use for qubit bring up, characterisation, and testing (characterisation for short) with over 100x speed up compared to current industry benchmarks, thereby removing a major bottleneck in the rate of development of quantum processing units (QPUs) and accelerating the path to developing practical quantum computers.
