Accurate ground state energy estimation with noise and imperfect state preparation
Alicja Dutkiewicz, Thomas E. O'Brien, Stefano Polla
We introduce a classical estimator for the post-processing of quantum phase estimation (QPE) data when a single target phase is isolated within a known interval, as is typical of g…
Plethysm is in #BQP
Matthias Christandl, Aram W. Harrow, Greta Panova +2
Some representation-theoretic multiplicities, such as the Kostka and the Littlewood-Richardson coefficients, admit a combinatorial interpretation that places their computation in t…
Adaptive quantum phase estimation can be better than non-adaptive
Noah Linden, Ronald de Wolf
Quantum phase estimation is one of the most important tools in quantum algorithms. It can be made non-adaptive (meaning all applications of the unitary happen simultaneously)…
Clifford testing: algorithms and lower bounds
Marcel Hinsche, Zongbo Bao, Philippe van Dordrecht +3
We consider the problem of Clifford testing, which asks whether a black-box -qubit unitary is a Clifford unitary or at least -far from every Clifford unitary. We gi…
Optimal Displacement Sensing with Spin-Dependent Squeezed States
Liam J. Bond, Christophe H. Valahu, Athreya Shankar +2
Displacement sensing is a fundamental task in metrology. However, the development of quantum-enhanced sensors that fully utilize the available degrees of freedom in many-body quant…
Anticoncentration is (almost) all you need
Markus Heinrich, Jonas Haferkamp, Ingo Roth +1
Until very recently, it was generally believed that the (approximate) 2-design property is strictly stronger than anticoncentration of random quantum circuits, mainly because it wa…
