Ramesh Rao, director of the Qualcomm Institute (QI) at UC San Diego and professor of Electrical and Computer Engineering (ECE) at UC San Diego’s Jacobs School of Engineering, sits down with Shane ...
Among the current challenges with creating quantum computers is that the timespan that a singular qubit remains coherent is quite limited, restricting their usefulness. Usually such qubits consist ...
BERKELEY, Calif.,– Quantum-classical computing company Rigetti announced the launch of its flagship 84-qubit Ankaa-3 system featuring a hardware redesign. Rigetti ...
This includes a new cryogenic hardware design to reduce the amount of metal at the refrigerator’s coldest stage, increasing efficiency and reducing the cost per qubit, and an improved qubit chip ...
Key design features include: – Cryogenic Hardware Design: Enhanced thermalization and shielding reduce noise and support the development of larger qubit systems. – Josephson Junction ...
The operation falls apart if researchers do anything at all to observe the state of a qubit while it's working. Austrian physicist Erwin Schrödinger famously compared this concept to having a cat ...
On one hand, charge noise in the qubit operation process is deeply suppressed. Charge noise has long been a troublesome issue in the field of quantum control, acting like an "invisible ...
