-Corrected Heisenberg Limit
Wojciech Gorecki, Rafal Demkowicz-Dobrzanski, Howard M. Wiseman +1
We consider the precision with which the parameter , appearing in the unitary map acting on some type of probe system, can be estimated when there is a fin…
Time-dependent Hamiltonian simulation with -norm scaling
Dominic W. Berry, Andrew M. Childs, Yuan Su +2
The difficulty of simulating quantum dynamics depends on the norm of the Hamiltonian. When the Hamiltonian varies with time, the simulation complexity should only depend on this qu…
Photonic quantum data locking
Zixin Huang, Peter P. Rohde, Dominic W. Berry +3
Quantum data locking is a quantum phenomenon that allows us to encrypt a long message with a small secret key with information-theoretic security. This is in sharp contrast with cl…
Improved Fault-Tolerant Quantum Simulation of Condensed-Phase Correlated Electrons via Trotterization
Ian D. Kivlichan, Craig Gidney, Dominic W. Berry +9
Recent work has deployed linear combinations of unitaries techniques to reduce the cost of fault-tolerant quantum simulations of correlated electron models. Here, we show that one…
Qubitization of Arbitrary Basis Quantum Chemistry Leveraging Sparsity and Low Rank Factorization
Dominic W. Berry, Craig Gidney, Mario Motta +2
Recent work has dramatically reduced the gate complexity required to quantum simulate chemistry by using linear combinations of unitaries based methods to exploit structure in the…
