“…A good understanding of the nonlinear behavior of this Josephson photonic crystal opens door to further more fundamental experiments with such devices. Finally, we demonstrated the possibility to implement TWPA made from SQUID, which could lead in the future to third-order Kerr nonlinearity TWPA, based on the SNAIL geometry [17,[55][56][57] or to TWPA with vanishingly small fourth-order Kerr nonlinearity [58,59]. Methods Theoretical model.…”

An amplifier combining noise performances as close as possible to the quantum limit with large bandwidth and high saturation power is highly desirable for many solid state quantum technologies such as high fidelity qubit readout or high sensitivity electron spin resonance for example. Here we introduce a new Traveling Wave Parametric Amplifier based on Superconducting QUantum Interference Devices. It displays a 3 GHz bandwidth, a −102 dBm 1-dB compression point and added noise near the quantum limit. Compared to previous state-of-the-art, it is an order of magnitude more compact, its characteristic impedance is in-situ tunable and its fabrication process requires only two lithography steps.The key is the engineering of a gap in the dispersion relation of the transmission line. This is obtained using a periodic modulation of the SQUID size, similarly to what is done with photonic crystals. Moreover, we provide a new theoretical treatment to describe the non-trivial interplay between non-linearity and such periodicity. Our approach provides a path to co-integration with other quantum devices such as qubits given the low footprint and easy fabrication of our amplifier. arXiv:1907.10158v1 [cond-mat.mes-hall]

“…It was demonstrated that feeding the amplifier with bimodal Fock input states leads to a quantification for the noise estimators that is within the SQLs, while when exploiting bimodal coherent input states these limits can be exceeded. The results represent a key model to predict the behaviour of rf-SQUID based JTWPA [18], [19] and other Josephson-based metamaterials [23] for quantum computing (via quantum limited amplification of complex signals) [17], [26], [27] and for quantum information (via the generation of non-classical radiation [5]- [8], [28]) in non-ideal cryogenic environment [29].…”

The advent of ultra-low noise microwave amplifiers revolutionized several research fields demanding quantum-analyze some of the intrinsic properties of a model architecture (i.e., an rf-SQUID based Josephson Traveling Wave Parametric Amplifier) in terms of amplification and noise generation for key case study input states (Fock and coherents). Furthermore, we present an analysis of the output signals generated by the parametric amplification mechanism when thermal noise fluctuations feed the device.

“…These devices could be used as Josephson Traveling Wave Parametric Amplifiers, based on four-wave mixing [10,11,22]. Their fluxtunability offers interesting perspectives regarding threewave mixing [34,35] or Kerr-free [36,37] J-TWPA. These devices could also be used to perform new quantum optics experiments in the microwave domain [38].…”

We report on the fabrication and characterization of 50 Ω, flux-tunable, low-loss, SQUID-based transmission lines. The fabrication process relies on the deposition of a thin dielectric layer (few tens of nanometers) via Atomic Layer Deposition (ALD) on top of a SQUID array, the whole structure is the covered by a non-superconducting metallic top ground plane. We present experimental results from five different samples. We systematically characterize their microscopic parameters by measuring the propagating phase in these structures. We also investigate losses and discriminate conductor from dielectric losses. This fabrication method offers several advantages. First, the SQUID array fabrication does not rely on a Niobium tri-layer process but on a simpler double angle evaporation technique. Second, ALD provides high quality dielectric leading to low-loss devices. Further, the SQUID array fabrication is based on a standard, all-aluminum process, allowing direct integration with superconducting qubits. Moreover, our devices are in-situ flux tunable, allowing mitigation of incertitude inherent to any fabrication process. Finally, the unit cell being a single SQUID (no extra ground capacitance is needed), it is straightforward to modulate the size of the unit cell periodically, allowing band-engineering. This fabrication process can be directly applied to traveling wave parametric amplifiers. arXiv:1907.10162v1 [cond-mat.mes-hall]
