Fermionic entanglement in the Lipkin model
M. Di Tullio, R. Rossignoli, M. Cerezo +1
We examine the fermionic entanglement in the ground state of the fermionic Lipkin model and its relation with bipartite entanglement. It is first shown that the one-body entangleme…
Noise Resilience of Variational Quantum Compiling
Kunal Sharma, Sumeet Khatri, M. Cerezo +1
Variational hybrid quantum-classical algorithms (VHQCAs) are near-term algorithms that leverage classical optimization to minimize a cost function, which is efficiently evaluated o…
Strong bound between trace distance and Hilbert-Schmidt distance for low-rank states
Patrick J. Coles, M. Cerezo, Lukasz Cincio
The trace distance between two quantum states, and , is an operationally meaningful quantity in quantum information theory. However, in general it is difficult to compute, i…
