Classical and Quantum Simulation of All-to-All Quantum Dynamics in Logarithmic Space
Maximilian Lutz, Rahul Trivedi, J. Ignacio Cirac
We study both the classical and the quantum complexity of the problem of estimating disorder-averaged quench dynamics for all-to-all spin Hamiltonians such as quantum Hopfield, She…
Measurement and feedforward circuits from quantum error correcting codes
Georgios Styliaris, Rahul Trivedi
Measurements and feedforward enhance the power of shallow quantum circuits, enabling the deterministic implementation of global unitary operations and the preparation of long-range…
Is rapid mixing stable?
Jordi A. Montañà-López, Barbara Roos, Sebastian Stengele +2
Several physically interesting Lindbladians, such as those describing generic open quantum system models as well as engineered state preparation processes, are often rapidly mixing…
Dissipative preparation of injective tensor network states
Drishti Baruah, Georgios Styliaris, J. Ignacio Cirac +1
The preparation of tensor network states is a fundamental prerequisite for a wide range of quantum simulation tasks. While many unitary protocols for preparing these states have be…
Sequential Measurements as a Resource in Ancilla-Assisted Quantum Metrology
Koray Mentesoglu, Rahul Trivedi, Sara Mouradian
We present a protocol for simultaneous estimation of both quadratures of a displacement channel on a quantum harmonic oscillator using a single ancilla qubit, without complex state…
Structure and Classification of Matrix Product Quantum Channels
Giorgio Stucchi, J. Ignacio Cirac, Rahul Trivedi +1
We develop a framework for Matrix Product Quantum Channels (MPQCs), a one-dimensional tensor-network description of completely positive, trace-preserving maps. We focus on translat…
Quantum Memory and Autonomous Computation in Two Dimensions
Gesa Dünnweber, Georgios Styliaris, Rahul Trivedi
Quantum error correction (QEC) normally requires active maintenance using measurements, classical processing and externally controlled correction schedules. Passive QEC, by contras…
