This paper provides a precise description of LOCC and related operational classes in terms of quantum instruments that captures both finite round protocols as well as those that utilize an unbounded number of communication rounds.Expand

This work solves an open problem by constructing quantum walks that not only detect but also find marked vertices in a graph by introducing a notion of interpolation between the random walk P and the absorbing walk P, whose marked states are absorbing.Expand

We consider a communication method, where the sender encodes n classical bits into 1 qubit and sends it to the receiver who performs a certain measurement depending on which of the initial bits must… Expand

Convincing correlation between the bilateral differences in the local blood pressure and in the corresponding PWTT delay has been established, and the average value of leg stenosis diagnostic threshold was established to be in the range of 23 +/- 9 ms, with full reliability above 32 ms.Expand

It is shown that for any number of uses, there are channels for which the coherent information is zero, but which nonetheless have capacity, and that only a finite number of channel uses is always sufficient.Expand

This Letter introduces cluster parameters K and d of a quantum circuit and proposes a cluster simulation scheme that can simulate any (K,d)-clustered quantum circuit on a d-qubit machine in time roughly 2^{O(K)}, with further speedups possible when taking more fine-grained circuit structure into account.Expand

A class of EPI analogues for d-level quantum systems (i.e., qudits) are established for continuous-variable quantum systems, where X and Y are replaced by bosonic fields and the addition rule is the action of a beam splitter with transmissivity a on those fields.Expand

This work investigates the sample complexity of Hamiltonian simulation, and provides protocols for running more-complex quantum programs specified by several different states, and gives a protocol for creating a coherent superposition of pure states, when given sample access to those states.Expand

It is shown that below a critical frequency of the external field the trajectory of a particle is a circle and for frequencies slightly above the critical point the particle moves on an approximately circular trajectory and from time to time jumps to another region of space.Expand

This paper combines TML with a temporal logic to obtain a new logic, so that the users can specify the dynamics of trust and model evolving theories of trust for multi-agent systems.Expand
