Mechanically induced correlated errors on superconducting qubits with relaxation times exceeding 0.4 ms

Tobias Kippenberg, Amir Youssefi, Marco Scigliuzzo, Mahdi Chegnizadeh, Shingo Kono, Xuxin Wang

Superconducting qubits are among the most advanced candidates for achieving fault-tolerant quantum computing. Despite recent significant advancements in the qubit lifetimes, the origin of the loss mechanism for state-of-the-art qubits is still subject to i ...

Completion of the Commissioning of the EDIPO Test Facility

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Rainer Wesche, Stephen Alfred March

The main coils of the new European DIPOle (EDIPO) test facility, which is able to provide a background magnetic field up to 12.35 T, were commissioned at the Center for Research in Plasma Physics in July 2013. A field homogeneity of +/-1% was achieved over ...

An ultra-low temperature scanning Hall probe microscope for magnetic imaging below 40 mK

Henrik Moodysson Rønnow, Julian Piatek

We describe the design of a low temperature scanning Hall probe microscope (SHPM) for a dilution refrigerator system. A detachable SHPM head with 25.4 mm OD and 200 mm length is integrated at the end of the mixing chamber base plate of the dilution refrige ...

Parametric study for the cooling of high temperature superconductor (HTS) current leads

Rainer Wesche

The analysis of cooling of a binary HTS 20 kA current lead (CL) operating between 4.5 and 300 K has been carried out. Assuming that the HTS module is conduction-cooled, two cooling options for the copper heat exchanger (HEX) part of the CL have been consid ...

Dynamical photothermal response of optical whispering-gallery silica microresonators in helium-4 cryogenic environments

Tobias Kippenberg, Xiaoqing Zhou, Albert Schliesser

We present optical measurements of the photothermal response of a whispering-gallery silica microresonator in a helium-4 exchange gas cryostat. Using transient-mode numerical simulations, we discuss the various heat propagation mechanisms. (C) 2011 Optical ...

Thermo-hydraulic analysis of the cool-down of the EDIPO test facility

The first cool-down of the EDIPO (European DIPOle) test facility is foreseen to take place in 2011 by means of the existing 1.2 kW cryoplant at EPFL-CRPP Villigen. In this work, the thermo-hydraulic analysis of the EDIPO cool-down is performed in order bot ...

Modeling of a two-stage magnetic refrigerator with wavy-structure gadolinium heat exchangers

Didier Albert Simon Vuarnoz, Cyrill Gonin

In a rotary magnetic refrigerator a porous ring is turning in and out of a magnetic field region. The adiabatic demagnetization of the magnetocaloric material produces the "cold energy". This is described by a discontinuous temperature decrease, known as a ...
