Josephson -junction in nanowire quantum dots
D. B. Szombati, S. Nadj-Perge, D. Car +3
The Josephson effect describes supercurrent flowing through a junction connecting two superconducting leads by a thin barrier [1]. This current is driven by a superconducting phase…
Effects of the electrostatic environment on the Majorana nanowire devices
A. Vuik, D. Eeltink, A. R. Akhmerov +1
One of the promising platforms for creating Majorana bound states is a hybrid nanostructure consisting of a semiconducting nanowire covered by a superconductor. We analyze the prev…
High Kinetic Inductance Superconducting Nanowire Resonators for Circuit QED in a Magnetic Field
N. Samkharadze, A. Bruno, P. Scarlino +4
We present superconducting microwave-frequency resonators based on NbTiN nanowires. The small cross section of the nanowires minimizes vortex generation, making the resonators resi…
Assessing the performance of quantum repeaters for all phase-insensitive Gaussian bosonic channels
Kenneth Goodenough, David Elkouss, Stephanie Wehner
One of the most sought-after goals in experimental quantum communication is the implementation of a quantum repeater. The performance of quantum repeaters can be assessed by compar…
Edge Transport in the Trivial Phase of InAs/GaSb
Fabrizio Nichele, Henri J. Suominen, Morten Kjaergaard +16
We present transport and scanning SQUID measurements on InAs/GaSb double quantum wells, a system predicted to be a two-dimensional topological insulator. Top and back gates allow i…
Entropic uncertainty and measurement reversibility
Mario Berta, Stephanie Wehner, Mark M. Wilde
The entropic uncertainty relation with quantum side information (EUR-QSI) from [Berta et al., Nat. Phys. 6, 659 (2010)] is a unifying principle relating two distinctive features of…
(Nearly) optimal P-values for all Bell inequalities
David Elkouss, Stephanie Wehner
A key objective in conducting a Bell test is to quantify the statistical evidence against a local-hidden variable model (LHVM) given that we can collect only a finite number of tri…
Continuous-Variable Protocols in the Noisy-Storage Model
Fabian Furrer, Christian Schaffner, Stephanie Wehner
We present the first protocol for oblivious transfer that can be implemented with an optical continuous-variable system, and prove its security in the noisy-storage model. This mod…
Disorder-induced topological transitions in multichannel Majorana wires
B. Pekerten, A. Teker, O. Bozat +2
In this work, we investigate the effect of disorder on the topological properties of multichannel superconductor nanowires. While the standard expectation is that the spectral gap…
Independent, extensible control of same-frequency superconducting qubits by selective broadcasting
S. Asaad, C. Dickel, S. Poletto +5
A critical ingredient for realizing large-scale quantum information processors will be the ability to make economical use of qubit control hardware. We demonstrate an extensible st…
Experimental loophole-free violation of a Bell inequality using entangled electron spins separated by 1.3 km
B. Hensen, H. Bernien, A. E. Dréau +16
For more than 80 years, the counterintuitive predictions of quantum theory have stimulated debate about the nature of reality. In his seminal work, John Bell proved that no theory…
Optimized quantum sensing with a single electron spin using real-time adaptive measurements
Cristian Bonato, Machiel S. Blok, Hossein T. Dinani +4
Quantum sensors based on single solid-state spins promise a unique combination of sensitivity and spatial resolution. The key challenge in sensing is to achieve minimum estimation…
Dynamical error bounds for continuum discretisation via Gauss quadrature rules, -- a Lieb-Robinson bound approach
Mischa P. Woods, Martin B. Plenio
Instances of discrete quantum systems coupled to a continuum of oscillators are ubiquitous in physics. Often the continua are approximated by a discrete set of modes. We derive ana…
Broadband architecture for galvanically accessible superconducting microwave resonators
Sal J. Bosman, Vibhor Singh, Alessandro Bruno +1
In many hybrid quantum systems, a superconducting circuit is required that combines DC-control with a coplanar waveguide (CPW) microwave resonator. The strategy thus far for applyi…
Repeated quantum error correction on a continuously encoded qubit by real-time feedback
Julia Cramer, Norbert Kalb, M. Adriaan Rol +6
Reliable quantum information processing in the face of errors is a major fundamental and technological challenge. Quantum error correction protects quantum states by encoding a log…
Single-Spin CCD
Timothy Alexander Baart, Mohammad Shafiei, Takafumi Fujita +3
Spin-based electronics or spintronics relies on the ability to store, transport and manipulate electron spin polarization with great precision. In its ultimate limit, information i…
Work and reversibility in quantum thermodynamics
Álvaro M. Alhambra, Stephanie Wehner, Mark M. Wilde +1
It is a central question in quantum thermodynamics to determine how irreversible is a process that transforms an initial state to a final state , and whether such irreversib…
Sifting attacks in finite-size quantum key distribution
Corsin Pfister, Norbert Lütkenhaus, Stephanie Wehner +1
A central assumption in quantum key distribution (QKD) is that Eve has no knowledge about which rounds will be used for parameter estimation or key distillation. Here we show that…
The maximum efficiency of nano heat engines depends on more than temperature
Mischa P. Woods, Nelly Ng, Stephanie Wehner
Sadi Carnot's theorem regarding the maximum efficiency of heat engines is considered to be of fundamental importance in thermodynamics. This theorem famously states that the maximu…
Asynchronous reference frame agreement in a quantum network
Tanvirul Islam, Stephanie Wehner
An efficient implementation of many multiparty protocols for quantum networks requires that all the nodes in the network share a common reference frame. Establishing such a referen…
