Noisy Quantum Trees: Infinite Protection Without Correction
Shiv Akshar Yadavalli, Iman Marvian
We study quantum networks with tree structures, in which information propagates from a root to leaves. At each node in the network, the received qubit unitarily interacts with fres…
Sufficient statistic and recoverability via Quantum Fisher Information metrics
Li Gao, Haojian Li, Iman Marvian +1
We prove that for a large class of quantum Fisher information, a quantum channel is sufficient for a family of quantum states, i.e., the input states can be recovered from the outp…
Theory of Quantum Circuits with Abelian Symmetries
Iman Marvian
Quantum circuits with gates (local unitaries) respecting a global symmetry have broad applications in quantum information science and related fields, such as condensed matter theor…
Rotationally-Invariant Circuits: Universality with the exchange interaction and two ancilla qubits
Iman Marvian, Hanqing Liu, Austin Hulse
Universality of local unitary transformations is one of the cornerstones of quantum computing with many applications and implications that go beyond this field. However, it has bee…
Operational Interpretation of Quantum Fisher Information in Quantum Thermodynamics
Iman Marvian
In the framework of quantum thermodynamics preparing a quantum system in a general state requires the consumption of two distinct resources, namely, work and coherence. It has been…
Qudit circuits with SU(d) symmetry: Locality imposes additional conservation laws
Iman Marvian, Hanqing Liu, Austin Hulse
Local symmetric quantum circuits provide a simple framework to study the dynamics and phases of complex quantum systems with conserved charges. However, some of their basic propert…
