Query: Proximity nanovalve with large phase-tunable thermal conductance   We propose a phase-controlled heat-flux quantum valve based on the proximity
effect driven by a superconducting quantum interference proximity transistor
(SQUIPT). Its operation relies on the phase-dependent quasiparticle density of
states in the Josephson weak-link of the SQUIPT which controls thermal
transport across the device. In a realistic Al/Cu-based setup the structure can
provide efficient control of thermal current inducing temperature swings
exceeding $\sim100$~mK, and flux-to-temperature transfer coefficients up to
$\sim 500$~mK/$\Phi_0$ below 100~mK. The nanovalve performances improve by
lowering the bath temperature, making the proposed structure a promising
building-block for the implementation of coherent caloritronic devices
operating below 1~K.
