Abstract:

This article presents a cryogenic quantum interface chipset at 3.5 K for superconducting transmon qubit operations. The chipset comprises a phase-detection readout and a phase-shifter-based polar-modulation controller with flexible scalability. With the proposed phase-detection readout scheme, a 9-bit time-to-digital converter (TDC)-based state detector is used to read out the qubit …

Abstract:

Millions of quantum-bits (qubits) are envisioned for a fault-tolerant quantum computer. For scalability, silicon spin qubit stands out due to its compatibility with advanced CMOS processes. Silicon single-electron transistors (SETs) are widely adopted for the quantum state discrimination of spin qubits. For high-fidelity quantum logic gate and readout, the gate …
