Can insights from topology—the study of the properties ... A Kerr nonlinear oscillator can be used as a qubit in quantum computing, as it can generate two simultaneous opposite states.

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 ...

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 ...

The Contralto also offers unique customizability, with the option to add chip features as desired, such as asymmetric squid junctions, Purcell filters, and custom qubit topology. Meanwhile, dedicated ...

Enhancements across the technology stack include a new cryogenic hardware design, an overhaul of the qubit circuit layout, precise qubit frequency targeting with Alternating-Bias Assisted ...

By analogy, a conventional qubit would be as if you used a string ... The new qubits are the same, encoding data in the topology of the material. In practice, Quantinuum’s H1 processor uses ...

Rigetti Computing (RGTI) announced the public launch of its 84-qubit Ankaa-3 system. Ankaa-3 is Rigetti’s newest flagship quantum computer featuring an extensive hardware redesign that enables ...
