Molybdenum Rhenium (MoRe)

Emerging Alloy for Resilient Qubit Circuits

Role in quantum circuits

Josephson junction electrodes, qubit wiring in magnetic-field-tolerant and hybrid

designs

Why it matters

MoRe alloys offer a tunable Tc and are highly compatible with silicon nanofabrication

processes. They are being explored for qubit designs that must tolerate small magnetic fields, including topological qubit experiments using Majorana zero modes in semiconductor-superconductor hybrid systems.

Key facts

• Tc tunable by adjusting the Mo:Re ratio during co-sputtering

• Compatible with semiconductor (Si) foundry fabrication processes

• Used in hybrid semiconductor-superconductor qubit devices

• Relevant for topological-qubit material stacks

• Useful for evaluating semiconductor-superconductor integration paths
