Abstract

We show that the equilibrium noise can be dramatically suppressed in the case of a tunnel junction with modulated (time-dependent) transparency. We demonstrate how such a contact could be used either as an optimal electron entangler or as a single-electron source with suppressed equilibrium noise at low temperatures.

Reverse Engineering with Quantum Noise

Muhammed Yönaç, Joseph H. Eberly

We show that specific quantum noise, acting as an open-system reservoir for non-locally entangled atoms, can serve to preserve rather than degrade joint coherence. This creates a new type of long-time control over hiding and recovery of quantum entanglement.

Optimization of charge sensitivity of a single electron tunneling transistor with a superconducting grain

Ulrik Hanke, K. A. Chao, Y. M. Galperin

Assuming the absence of 1/f noise, we have calculated the charge sensitivity (CS) of a capacitive-coupled double-junction single electron tunneling transistor (SETT) with a superconducting grain, operating at low temperature and low bias voltage such that the tunneling current is dominated by the Andreev process. In this case the effect of co-tunneling is suppressed without using the complicated fabrication method. We have used a realistic sample to demonstrate the procedure of optimizing the CS of a SETT with respect to relevant physical parameters and structure parameters. With the presently available fabrication technology, our theoretical analysis can serve as a guide for increasing the CS of a SETT beyond 10−6 e/√Hz.

Optimal Cold-Electron Bolometer with a Superconductor-Insulator-Normal Tunnel Junction and an Andreev Contact

L. S. Kuzmin

A novel concept of the optimal Cold-Electron Bolometer (CEB) with a Superconductor-Insulator-Normal (SIN) Tunnel Junction and Andreev SN contact has been proposed. This concept has been developed to improve noise properties of the CEB by increasing current responsivity for SQUID readout (in voltage-biased mode) in comparison with classical CEB concept comprising two SIN tunnel junctions. In this configuration the power of incoming signal is not split between two series junctions and the current response of a single junction is twice larger in comparison with double junction structure. The signal is concentrated from antenna to an absorber through capacitance of the tunnel junction from one side and Andreev contact from another side. HF matching is realized by resistance of a normal metal absorber that is independent on tunnel junction parameters. The volume of a normal metal is partly squeezed due to proximity effect of a superconducting electrode from the Andreev contact that also increases efficiency of the electron cooling. The concept is based on direct electron cooling of the absorber by SIN tunnel junction that serves as negative electrothermal feedback for the signal. Noise properties are considerably improved by decreasing the electron temperature. Ultimate performance of the CEB is determined by optical load converted to shot noise of the signal readout. The goal is to achieve noise-equivalent power (NEP) of the CEB with standard SQUID readout less than photon noise. Ultimate NEP better than photon noise can be achieved practically in wide range of power loads from 0.1 fW (SPICA) to 30 pW (OLIMPO, CLOVER, PILOT). Applicability of the CEB to post-Herschel space missions looks very promising.

Detection mechanisms in superconducting point contacts at frequencies of 44 times the energy gap

Donald G. McDonald, F. R. Petersen, J. D. Cupp +2 more

We have performed mixing experiments with CO2 lasers in the 9 to 11 μm wavelength band using superconducting point contacts. The experiments involve difference frequencies ranging from 19 MHz to 106 GHz. The mixing mechanism definitely appears to require the superconducting state since the beat signal amplitude decreases by as much as 60 dB as the bath temperature is raised through the superconducting transition temperature. At least three conceptually distinguishable mechanisms may be involved in the observed response. These include : (1) a conventional Josephson response, (2) a thermally modulated Josephson response, and (3) a single particle tunneling response. The usual signature of a Josephson interaction is one or more current steps in the I-V curve. Steps, the first of which should be at 67 mV, are not observed in these experiments. However, we do not feel that is a definitive test for the mixing mechanism between two external sources at such high frequencies. In fact, Werthamer's theory of tunnel junctions predicts a large response for these experiments, a response as large as that from two X-band sources, for example. It should be noted, however, that the theory assumes the junction is maintained at a fixed low temperature and whether or not that is the case depends directly on the current density at the contact. Very little is known about the current density at the present time. These experiments emphasize a fact that is usually overlooked in Josephson junction mixing experiments with an external local oscillator. If the contact or tunneling region is sufficiently small, it may be thermally modulated at difference frequencies extending into the microwave range. This effect becomes more likely with increasing applied frequencies, particularly in the infrared. Theoretical modeling for the purpose of calculating ultimate sensitivities of these devices requires a detailed consideration of thermal effects. We fully expect large mixing signals from Josephson junctions even at optical frequencies if thermal effects do not prove to be a limitation.
