Implementing Jastrow--Gutzwiller operators on a quantum computer using the cascaded variational quantum eigensolver algorithm
John P. T. Stenger, C. Stephen Hellberg, Daniel Gunlycke
A Jastrow--Gutzwiller operator adds many-body correlations to a quantum state. However, the operator is non-unitary, making it difficult to implement directly on a quantum computer…
Cascaded variational quantum eigensolver algorithm
Daniel Gunlycke, C. Stephen Hellberg, John P. T. Stenger
We present a cascaded variational quantum eigensolver algorithm that only requires the execution of a set of quantum circuits once rather than at every iteration during the paramet…
Simulating spectroscopy experiments with a superconducting quantum computer
John P. T. Stenger, Gilad Ben-Shach, David Pekker +1
We present a novel method for solving eigenvalue problems on a quantum computer based on spectroscopy. The method works by coupling a "probe" qubit to a set of system simulation qu…
Expanding variational quantum eigensolvers to larger systems by dividing the calculations between classical and quantum hardware
John P. T. Stenger, Daniel Gunlycke, C. Stephen Hellberg
We present a hybrid classical/quantum algorithm for efficiently solving the eigenvalue problem of many-particle Hamiltonians on quantum computers with limited resources by splittin…
Triple Andreev dot chains in semiconductor nanowires
Hao Wu, Po Zhang, John P. T. Stenger +6
Kitaev chain is a theoretical model of a one-dimensional topological superconductor with Majorana zero modes at the two ends of the chain. With the goal of emulating this model, we…
Integrating micromagnets and hybrid nanowires for topological quantum computing
Malcolm J. A. Jardine, John P. T. Stenger, Yifan Jiang +4
Majorana zero modes are expected to arise in semiconductor-superconductor hybrid systems, with potential topological quantum computing applications. One limitation of this approach…
Simulating the dynamics of braiding of Majorana zero modes using an IBM quantum computer
John P. T. Stenger, Nicholas T. Bronn, Daniel J. Egger +1
We simulate the dynamics of braiding Majorana zero modes on an IBM Quantum computer. We find the native quantum gates introduce too much noise to observe braiding. Instead, we use…
1D Error Correcting Code for Majorana Qubits
John P. T. Stenger, Roger S. K. Mong
Although Majorana platforms are promising avenues to realizing topological quantum computing, they are still susceptible to errors from thermal noise and other sources. We show tha…
Weyl points in systems of multiple semiconductor-superconductor quantum dots
John P. T. Stenger, David Pekker
As an analogy to the Weyl point in k-space, we search for energy levels which close at a single point as a function of a three dimensional parameter space. Such points are topologi…
Braidonium: a braiding quantum circuit based on the Josephson effect
John P. T. Stenger, Michael Hatridge, Sergey M. Frolov +1
We propose a topological qubit in which braiding and readout are mediated by the Majorana-Josephson effect. The braidonium device consists of three Majorana nanowires that com…
Control and detection of Majorana bound states in quantum dot arrays
John P. T. Stenger, Benjamin D. Woods, Sergey M. Frolov +1
We study the low-energy physics of a one-dimensional array of superconducting quantum dots realized by proximity coupling a semiconductor nanowire to multiple superconducting islan…
Tunneling conductance in semiconductor-superconductor hybrid structures
John Stenger, Tudor D. Stanescu
We study the differential conductance for charge tunneling into a semiconductor wire--superconductor hybrid structure, which is actively investigated as a possible scheme for reali…
