Parallel Simulation of Quantum Networks with Distributed Quantum State Management
Xiaoliang Wu, Alexander Kolar, Joaquin Chung +3
Quantum network simulators offer the opportunity to cost-efficiently investigate potential avenues to building networks that scale with the number of users, communication distance,…
CutQC: Using Small Quantum Computers for Large Quantum Circuit Evaluations
Wei Tang, Teague Tomesh, Martin Suchara +2
Quantum computing (QC) is a new paradigm offering the potential of exponential speedups over classical computing for certain computational problems. Each additional qubit doubles t…
Approaches to Constrained Quantum Approximate Optimization
Zain H. Saleem, Teague Tomesh, Bilal Tariq +1
We study the costs and benefits of different quantum approaches to finding approximate solutions of constrained combinatorial optimization problems with a focus on Maximum Independ…
SeQUeNCe: A Customizable Discrete-Event Simulator of Quantum Networks
Xiaoliang Wu, Alexander Kolar, Joaquin Chung +4
Recent advances in quantum information science enabled the development of quantum communication network prototypes and created an opportunity to study full-stack quantum network ar…
Quantum Divide and Compute: Hardware Demonstrations and Noisy Simulations
Thomas Ayral, François-Marie Le Régent, Zain Saleem +2
Noisy, intermediate-scale quantum computers come with intrinsic limitations in terms of the number of qubits (circuit "width") and decoherence time (circuit "depth") they can have.…
Term Grouping and Travelling Salesperson for Digital Quantum Simulation
Kaiwen Gui, Teague Tomesh, Pranav Gokhale +4
Digital simulation of quantum dynamics by evaluating the time evolution of a Hamiltonian is the initially proposed application of quantum computing. The large number of quantum gat…
Minimizing State Preparations in Variational Quantum Eigensolver by Partitioning into Commuting Families
Pranav Gokhale, Olivia Angiuli, Yongshan Ding +5
Variational quantum eigensolver (VQE) is a promising algorithm suitable for near-term quantum machines. VQE aims to approximate the lowest eigenvalue of an exponentially sized matr…
Leakage Suppression in the Toric Code
Martin Suchara, Andrew W. Cross, Jay M. Gambetta
Quantum codes excel at correcting local noise but fail to correct leakage faults that excite qubits to states outside the computational space. Aliferis and Terhal have shown that a…
Efficient Algorithms for Maximum Likelihood Decoding in the Surface Code
Sergey Bravyi, Martin Suchara, Alexander Vargo
We describe two implementations of the optimal error correction algorithm known as the maximum likelihood decoder (MLD) for the 2D surface code with a noiseless syndrome extraction…
Comparing the Overhead of Topological and Concatenated Quantum Error Correction
Martin Suchara, Arvin Faruque, Ching-Yi Lai +3
This work compares the overhead of quantum error correction with concatenated and topological quantum error-correcting codes. To perform a numerical analysis, we use the Quantum Re…
Performance and Error Analysis of Knill's Postselection Scheme in a Two-Dimensional Architecture
Ching-Yi Lai, Gerardo Paz, Martin Suchara +1
Knill demonstrated a fault-tolerant quantum computation scheme based on concatenated error-detecting codes and postselection with a simulated error threshold of 3% over the depolar…
Subsystem surface codes with three-qubit check operators
Sergey Bravyi, Guillaume Duclos-Cianci, David Poulin +1
We propose a simplified version of the Kitaev's surface code in which error correction requires only three-qubit parity measurements for Pauli operators XXX and ZZZ. The new code b…
Constructions and Noise Threshold of Topological Subsystem Codes
Martin Suchara, Sergey Bravyi, Barbara M. Terhal
Topological subsystem codes proposed recently by Bombin are quantum error correcting codes defined on a two-dimensional grid of qubits that permit reliable quantum information stor…
