Do quantum linear solvers offer advantage for networks-based system of linear equations?
Disha Shetty, Supriyo Dutta, Palak Chawla +5
In this exploratory numerical study, we assess the suitability of Quantum Linear Solvers(QLSs)toward providing a quantum advantage for Networks-based Linear System Problems (NLSPs)…
Fault tolerance against amplitude-damping noise using Bacon-Shor codes
Long D. H. My, Akshaya Jayashankar, Prabha Mandayam +1
Designing efficient fault tolerance schemes is crucial for building useful quantum computers. Most standard schemes assume no knowledge of the underlying device noise and rely on g…
Enhancing the Harrow-Hassidim-Lloyd (HHL) algorithm in systems with large condition numbers
Peniel Bertrand Tsemo, Akshaya Jayashankar, K. Sugisaki +3
Although the Harrow-Hassidim-Lloyd (HHL) algorithm offers an exponential speedup in system size for treating linear equations of the form on quantum computers wh…
Adapting the HHL algorithm to quantum many-body theory
Nishanth Baskaran, Abhishek Singh Rawat, Akshaya Jayashankar +6
Rapid progress in developing near- and long-term quantum algorithms for quantum chemistry has provided us with an impetus to move beyond traditional approaches and explore new ways…
Variational Quantum Circuits for Multi-Qubit Gate Automata
Arunava Majumder, Dylan Lewis, Akshaya Jayashankar +2
Implementing quantum operations in the form of natural Hamiltonian dynamics is desirable, since they almost require no external control or feedback. In this work, we propose a NISQ…
Quantum Error Correction: Noise-adapted Techniques and Applications
Akshaya Jayashankar, Prabha Mandayam
The quantum computing devices of today have tens to hundreds of qubits that are highly susceptible to noise due to unwanted interactions with their environment. The theory of quant…
Adaptive quantum codes: constructions, applications and fault tolerance
Akshaya Jayashankar
A major obstacle towards realizing a practical quantum computer is the noise that arises due to system-environment interactions. While it is very well known that quantum error corr…
Achieving fault tolerance against amplitude-damping noise
Akshaya Jayashankar, My Duy Hoang Long, Hui Khoon Ng +1
With the intense interest in small, noisy quantum computing devices comes the push for larger, more accurate -- and hence more useful -- quantum computers. While fully fault-tolera…
Finding good quantum codes using the Cartan form
Akshaya Jayashankar, Anjala M Babu, Hui Khoon Ng +1
We present a simple and fast numerical procedure to search for good quantum codes for storing logical qubits in the presence of independent per-qubit noise. In a key departure from…
Pretty good state transfer via adaptive quantum error correction
Akshaya Jayashankar, Prabha Mandayam
We examine the role of quantum error correction (QEC) in achieving pretty good quantum state transfer over a class of -d spin Hamiltonians. Recasting the problem of state transf…
