چکیده

Pulsed readout of Direct Current (DC) Superconducting Quantum Interference Device (SQUID) is crucial for experiments which need to be performed at millikelvin temperatures, such as the superconducting and electron spin based qubits. algorithms used in these are usually specific experimental setup require some optimization. We present a circuit that emulates behavior DC-SQUID order allow development evaluation pulsed room temperature without running dilution refrigerator. This novel also constitutes low cost device can teach principles courses aimed training next generation quantum engineers.

Dc - Squid Sensor System for Multichannel Neuromagnetometry

Various DC-SQUID sensor configurations were developed for use in our 19-channel neuromagnetometer. Apart from the standard type, resistively and inductively shunted SQUIDs were made, allowing for a large screening factor p (>l). In this way signal coupling from the pick-up coil to the SQUID is facilitated and capacitive coupling between the input coil and the SQUID washer can be decreased. The ...

Improving high-Tc dc-SQUID performance by junction asymmetry

We study noise and noise energy of a high-Tc dc SQUID fabricated on a high-ǫR substrate whose conduction properties are given by transmission line physics. We show that transmission line resonances greatly enhance the noise. Remarkably, resistance asymmetry enhances these resonances even more. However, as the transfer function (dc dφ ) scales the same way, the noise energy is reduced by asymmet...

Quantum analysis of a linear dc SQUID mechanical displacement detector

We provide a quantum analysis of a dc SQUID mechanical displacement detector within the subcritical Josephson current regime. A segment of the SQUID loop forms the mechanical resonator and motion of the latter is transduced inductively through changes in the flux threading the loop. Expressions are derived for the detector signal response and noise, which are used to evaluate the position and f...

One-shot quantum measurement using a hysteretic dc SQUID.

We propose a single shot quantum measurement to determine the state of a Josephson charge quantum bit (qubit). The qubit is a Cooper pair box and the measuring device is a two junction superconducting quantum interference device (dc SQUID). This coupled system exhibits a close analogy with a Rydberg atom in a high Q cavity, except that in the present device we benefit from the additional featur...
