# Compressed quantum computation using the IBM Quantum Experience

@inproceedings{Hebenstreit2017CompressedQC, title={Compressed quantum computation using the IBM Quantum Experience}, author={Martin Hebenstreit and Daniel Alsina and Jos{\'e} Ignacio Latorre and Barbara Kraus}, year={2017} }

The notion of compressed quantum computation is employed to simulate the Ising interaction of a 1D–chain consisting out of n qubits using the universal IBM cloud quantum computer running on log(n) qubits. The external field parameter that controls the quantum phase transition of this model translates into particular settings of the quantum gates that generate the circuit. We measure the magnetization, which displays the quantum phase transition, on a two–qubit system, which simulates a four…

An explicit scheme (quantum circuit) is designed for the teleportation of an n-qubit quantum state. It is established that the proposed scheme requires an optimal amount of quantum resources, whereas…

### Design and experimental realization of an optimal scheme for teleportation of an n-qubit quantum state

- PhysicsQuantum Inf. Process.
- 2017

It is established that the proposed scheme requires an optimal amount of quantum resources, whereas larger amount of physics resources have been used in a large number of recently reported teleportation schemes for the quantum states which can be viewed as special cases of the general n-qubit state considered here.

### QEnclave - A practical solution for secure quantum cloud computing

- Computer Science, Mathematicsnpj Quantum Information
- 2022

While previous delegated protocols relied on a client that can either generate or measure quantum states, it is shown that this same functionality can be achieved with a Client that only transforms quantum states without generating or measuring them.

### Conditional Hybrid Nonclassicality.

- Computer SciencePhysical review letters
- 2017

The operational notion of conditional hybrid nonclassicality which relates to the ability to produce a non classical continuous-variable state by projecting onto a general superposition of discrete-variable subsystem is introduced.

### Remote optimization of an ultracold atoms experiment by experts and citizen scientists

- Computer ScienceProceedings of the National Academy of Sciences
- 2018

It is demonstrated that citizen scientists can also be successful in an entirely abstract problem visualization, which is encouraging because a much wider range of challenges could potentially be opened to gamification in the future.

### Experimental Realization of Secure Multiparty Quantum Summation Using Five-Qubit IBM Quantum Computer on Cloud

- Physics, Computer Science
