A theoretical study of nonclassical effects in optical and spin systems and their applications
Kishore Thapliyal·Mar 5, 2018
Nonclassical states, having no classical analogue, promise advantage in the performance in several fields of technology, such as computation, communication, sensing. This led to an escalated interest in the recent years for the generation and charact...
On-chip transverse-mode entangled photon pair source
Lantian Feng, Ming Zhang, X. Xiong +7 more·Feb 27, 2018
Integrated entangled photon pair source is an essential resource for both fundamental investigations and practical applications of quantum information science. Currently there have been several types of entanglement, among which the transverse-mode e...
Microscopic characterisation of laser-written phenomena for component-wise testing of photonic integrated circuits
J. Guan, Xiang Liu, A. Menssen +1 more·Feb 22, 2018
Photonic integrated circuits (PICs) directly written with a femtosecond laser have shown great potential in many areas such as quantum information processing (QIP). Many applications, like photon-based quantum computing, demand the up-scaling of PICs...
Gaussian random number generator: Implemented in FPGA for quantum key distribution
Yue Hu, Yan Wu, Yi Chen +2 more·Feb 20, 2018
Quantum key distribution is the process of using quantum communication to establish a shared key between two parties. It has been demonstrated the unconditional security and effective communication of quantum communication system can be guaranteed by...
Realization of efficient quantum gates with a superconducting qubit-qutrit circuit
T. Bækkegaard, L. B. Kristensen, N. Loft +3 more·Feb 12, 2018
Building a quantum computer is a daunting challenge since it requires good control but also good isolation from the environment to minimize decoherence. It is therefore important to realize quantum gates efficiently, using as few operations as possib...
Deterministic Generation of Large-Scale Entangled Photonic Cluster State from Interacting Solid State Emitters.
Mercedes Gimeno-Segovia, T. Rudolph, S. Economou·Jan 8, 2018
The ability to create large highly entangled "cluster" states is crucial for measurement-based quantum computing. We show that deterministic multiphoton entanglement can be created from coupled solid state quantum emitters without the need for any tw...
Deterministic quantum state transfer and remote entanglement using microwave photons
P. Kurpiers, P. Magnard, T. Walter +10 more·Dec 22, 2017
Sharing information coherently between nodes of a quantum network is fundamental to distributed quantum information processing. In this scheme, the computation is divided into subroutines and performed on several smaller quantum registers that are co...
Deterministic delivery of remote entanglement on a quantum network
P. Humphreys, N. Kalb, Jaco P. J. Morits +5 more·Dec 20, 2017
Large-scale quantum networks promise to enable secure communication, distributed quantum computing, enhanced sensing and fundamental tests of quantum mechanics through the distribution of entanglement across nodes1–7. Moving beyond current two-node n...
Cluster state generation in one-dimensional Kitaev honeycomb model via shortcut to adiabaticity
T. Kyaw, L. Kwek·Dec 19, 2017
We propose a mean to obtain computationally useful resource states also known as cluster states, for measurement-based quantum computation, via transitionless quantum driving algorithm. The idea is to cool the system to its unique ground state and tu...

We present the first experimental realization of a quantum artificial life algorithm in a quantum computer. The quantum biomimetic protocol encodes tailored quantum behaviors belonging to living systems, namely, self-replication, mutation, interactio...
Molecular spin qudits for quantum algorithms.

Presently, one of the most ambitious technological goals is the development of devices working under the laws of quantum mechanics. One prominent target is the quantum computer, which would allow the processing of information at quantum level for pur...
A small quantum computer is needed to optimize fault-tolerant protocols
Pavithran Iyer, D. Poulin·Nov 13, 2017
As far as we know, a useful quantum computer will require fault-tolerant gates, and existing schemes demand a prohibitively large space and time overhead. We argue that a first generation quantum computer will be very valuable to design, test, and op...
Crosstalk error correction through dynamical decoupling of single-qubit gates in capacitively coupled singlet-triplet semiconductor spin qubits
Donovan Buterakos, R. Throckmorton, S. Das Sarma·Nov 6, 2017
In addition to magnetic field and electric charge noise adversely affecting spin qubit operations, performing single-qubit gates on one of multiple coupled singlet-triplet qubits presents a new challenge---crosstalk, which is inevitable (and must be ...

Promising applications of the anisotropic quantum Rabi model (AQRM) in broad parameter ranges are explored, which is realized with superconducting flux qubits simultaneously driven by two-tone time-dependent magnetic fields. Regarding the quantum pha...
