DOI: 10.1103/physrevb.100.064201
Abstract: Randomly-doped silicon has many competitive advantages for quantum computation; not only is it fast to fabricate but it could naturally contain high numbers of qubits and logic gates as a function of doping densities. We… read more here.

DOI: 10.1126/sciadv.aao3603
Abstract: Harnessing techniques from analog signal processing, we establish a new path for large-scale quantum computation. We show that parametric coupling techniques can be used to generate selective entangling interactions for multi-qubit processors. By inducing coherent… read more here.
