Variational Real-Time Dynamics on Reduced Operator Manifolds
Aeishah Ameera Anuar, PV Sriluckshmy, Riccardo Rossi +1
Accurate real-time simulation of correlated quantum systems remains challenging for both classical methods and near-term quantum hardware. We introduce operator-projected variation…
Quantum Assisted Ghost Gutzwiller Ansatz
P. V. Sriluckshmy, François Jamet, Fedor Šimkovic
The ghost Gutzwiller ansatz (gGut) embedding technique was shown to achieve comparable accuracy to the gold standard dynamical mean-field theory method in simulating real material…
On-Premises Superconducting Quantum Computer for Education and Research
Jami Rönkkö, Olli Ahonen, Ville Bergholm +13
With a growing interest in quantum technology globally, there is an increasing need for accessing relevant physical systems for education and research. In this paper we introduce a…
Optimal, hardware native decomposition of parameterized multi-qubit Pauli gates
P. V. Sriluckshmy, Vicente Pina-Canelles, Mario Ponce +3
We show how to efficiently decompose a parameterized multi-qubit Pauli (PMQP) gate into native parameterized two-qubit Pauli (P2QP) gates minimizing both the circuit depth and the…
Low-depth simulations of fermionic systems on square-grid quantum hardware
Manuel G. Algaba, P. V. Sriluckshmy, Martin Leib +1
We present a general strategy for mapping fermionic systems to quantum hardware with square qubit connectivity which yields low-depth quantum circuits, counted in the number of nat…
Reduced Density Matrix Sampling: Self-consistent Embedding and Multiscale Electronic Structure on Current Generation Quantum Computers
Jules Tilly, P. V. Sriluckshmy, Akashkumar Patel +6
We investigate fully self-consistent multiscale quantum-classical algorithms on current generation superconducting quantum computers, in a unified approach to tackle the correlated…
Fully Algebraic and Self-consistent Effective Dynamics in a Static Quantum Embedding
P. V. Sriluckshmy, Max Nusspickel, Edoardo Fertitta +1
Quantum embedding approaches involve the self-consistent optimization of a local fragment of a strongly correlated system, entangled with the wider environment. The `energy-weighte…
Critical scaling of the mutual information in two-dimensional disordered Ising models
P. V. Sriluckshmy, Ipsita Mandal
Renyi Mutual information (RMI), computed from second Renyi entropies, can identify classical phase transitions from their finite-size scaling at the critical points. We apply this…
Interplay between topology and disorder in a two-dimensional semi-Dirac material
P. V. Sriluckshmy, Kush Saha, Roderich Moessner
We investigate the role of disorder in a two-dimensional semi-Dirac material characterized by a linear dispersion in one, and a parabolic dispersion in the orthogonal, direction. U…
Spin liquid like Raman signatures in hyperkagome iridate NaIrO
Satyendra Nath Gupta, P. V. Sriluckshmy, Ashiwini Balodhi +5
Combining Raman scattering measurements with mean field calculations of the Raman response we show that Kitaev-like magnetic exchange is dominant in the hyperkagome iridate NaI…
Antiferromagnetism in the Hubbard model on the honeycomb lattice: a Two-Particle Self-Consistent study

The semimetal to antiferromagnet quantum phase transition of the Hubbard model on the honeycomb lattice has come to the forefront in the context of the proposal that a semimetal to…
