-VQE: Excited-state preparation of quantum many-body scars with shallow circuits
Eoin Carolan, Nathan Keenan, Gabriele Cenedese +1
We present and benchmark a type of variational quantum eigensolver (VQE), which we denote -VQE. It is designed to target mid-spectrum eigenstates and prepare quantum many-body s…
Operator growth and spread complexity in open quantum systems
Eoin Carolan, Anthony Kiely, Steve Campbell +1
Commonly, the notion of "quantum chaos'' refers to the fast scrambling of information throughout complex quantum systems undergoing unitary evolution. Motivated by the Krylov compl…
Robustness of controlled Hamiltonian approaches to unitary quantum gates
Eoin Carolan, Barış Çakmak, Steve Campbell
We examine the effectiveness and resilience of achieving quantum gates employing three approaches stemming from quantum control methods: counterdiabatic driving, Floquet engineerin…
Commutativity and the emergence of classical objectivity
Eoghan Ryan, Eoin Carolan, Steve Campbell +1
We examine how the ability of a system to redundantly proliferate relevant information about its pointer states is affected when it is coupled to multiple baths. To this end, we co…
Counterdiabatic control in the impulse regime
Eoin Carolan, Anthony Kiely, Steve Campbell
Coherent control of complex many-body systems is critical to the development of useful quantum devices. Fast perfect state transfer can be exactly achieved through additional count…
