Optimal four-copy detection of the three-tangle and its fault-tolerant cost
Federico Tomás B. Pérez, Berta Casas, I-Chi Chen +3
The three-tangle, , is a measure of genuine tripartite entanglement that distinguishes GHZ-type from W-type entanglement in pure three-qubit states. Here, we identify the stat…
Complexity separations for optimal matchgate-Clifford synthesis
Berta Casas, Diego García-Martín, Yuxuan Zhang
Clifford and matchgate circuits are canonical families of classically simulable quantum circuits. Their intersection, the matchgate-Clifford group, plays an important role in rando…
Warm Starts, Cold States: Exploiting Adiabaticity for Variational Ground-States
Ricard Puig, Berta Casas, Alba Cervera-Lierta +2
Reliable preparation of many-body ground states is an essential task in quantum computing, with applications spanning areas from chemistry and materials modeling to quantum optimiz…
Matchgate synthesis via Clifford matchgates and gates
Berta Casas, Paolo Braccia, Élie Gouzien +2
Matchgate unitaries are ubiquitous in quantum computation due to their relation to non-interacting fermions and because they can be used to benchmark quantum computers. Implementin…
