There are still new physics to discover in circuit-QED-like systems. We investigate coupling an encoded spin qubit to a superconductor resonator via qubit energy level curvature versus gate voltage [1].This approach enables quantum non-demolition readout with strength of tens to hundred MHz all while the qubit stays …

After almost two-decades of sustained effort in making spin- based qubits, silicon still has great promise as the technology of choice for future quantum computers.After a brief update on the field, I will discuss our recent work proposing new qubit and coupling approaches for silicon quantum dots that attempt …

Future quantum computers may utilize multiple types of encoded spin qubits each optimized for their role within the system, be it computation, communication, initialization, or readout. In this talk I will discuss a new encoded qubit, the so-called “always-on, exchange-only” (AEON) qubit, which offers a true sweet spot to charge …
