Quantum Computing

By building a unique, advanced machine, Rutgers scientists have created a structure with quantum qualities. The green window (right) is the main growth chamber where synthesis of the quantum "sandwiches" occurs. Within the amber window (left) are advanced characterization tools that uncover chemical and electronic properties of the grown quantum thin films without exposing them to air.

Scientists Merge Two “Impossible” Materials Into New Artificial Structure

Researchers developed a new interconnect that can support scalable, all-to-all communication between a series of superconducting quantum processors, enabling an information-carrying photon to travel between processors in a user-defined direction. The concept is illustrated here.

Microsoft’s ‘Quantum Transistor’ Brings Million-Qubit Computing Within Reach

Researchers found that they can control how tightly bound excitons (electron-hole pairs) are in a magnetic material by changing its magnetic state, which could lead to new ways to switch materials' properties for future technologies like spintronics.

Scientists Unlock Magnetic ‘Light Switch’ for Next-Generation Quantum Computers

This artist's concept shows a quantum refrigerator based on superconducting circuits. The device cools qubits to extremely low temperatures using three qubits: a hot qubit (top right), a cold qubit (bottom right), and a target qubit (bottom left). Heat from a nearby hot environment powers the process, allowing the refrigerator to extract thermal energy from the target qubit and release it into a cold environment. This brings the target qubit to a low-error ground state, ideal for quantum computing. The device was developed at the Myfab nanofabrication lab, Chalmers University of Technology, Sweden.

Self-Powered Quantum Refrigerator Sets New Cold Record for Computing

The researchers built a system (circuit diagram on the left) that can be controlled by microwave pulses (wiggly arrow) to turn on or off different operations. This system creates a special quantum state (cubic phase state) useful for fixing errors in quantum computers. The blue areas on the right show a unique property (Wigner negative regions) that proves this state is truly quantum.
