Towards Scalable Braiding: Topological Superconductivity Unlocked under Arbitrary Magnetic Field Directions in Curved Planar Josephson Junctions
Richang Huang, Yongliang Hu, Xianzhang Chen +4
The non-Abelian statistics of Majorana zero modes (MZMs) are central to fault-tolerant topological quantum computing. Planar Josephson junctions provide a particularly versatile pl…
The Quantum Internet (Technical Version)
Peter P. Rohde, Zixin Huang, Yingkai Ouyang +14
Following the emergence of quantum computing, the subsequent quantum revolution will be that of interconnecting individual quantum computers at global level. In the same way that c…
Homomorphic encryption of linear optics quantum computation on almost arbitrary states of light with asymptotically perfect security
Yingkai Ouyang, Si-Hui Tan, Joseph Fitzsimons +1
Future quantum computers are likely to be expensive and affordable outright by few, motivating client/server models for outsourced computation. However, the applications for quantu…
Composable secure multi-client delegated quantum computation
Monireh Houshmand, Mahboobeh Houshmand, Si-Hui Tan +1
The engineering challenges involved in building large scale quantum computers, and the associated infrastructure requirements, mean that when such devices become available it is li…
Client-friendly continuous-variable blind and verifiable quantum computing
Nana Liu, Tommaso F. Demarie, Si-Hui Tan +2
We present a verifiable and blind protocol for assisted universal quantum computing on continuous-variable (CV) platforms. This protocol is highly experimentally-friendly to the cl…
The resurgence of the linear optics quantum interferometer --- recent advances & applications
Si-Hui Tan, Peter P. Rohde
Linear optics has seen a resurgence for applications in quantum information processing owing to its miniaturisation on-chip, and increase in production efficiency and quality of si…
Experimental Quantum Homomorphic Encryption
Jonas Zeuner, Ioannis Pitsios, Si-Hui Tan +4
Quantum computers promise not only to outperform classical machines for certain important tasks, but also to preserve privacy of computation. For example, the blind quantum computi…
Practical quantum somewhat-homomorphic encryption with coherent states
Si-Hui Tan, Yingkai Ouyang, Peter P. Rohde
We present a scheme for implementing homomorphic encryption on coherent states encoded using phase-shift keys. The encryption operations require only rotations in phase space, whic…
Computing on quantum shared secrets
Yingkai Ouyang, Si-Hui Tan, Liming Zhao +1
A (k,n)-threshold secret-sharing scheme allows for a string to be split into n shares in such a way that any subset of at least k shares suffices to recover the secret string, but…
Overarching framework between Gaussian quantum discord and Gaussian quantum illumination
Mark Bradshaw, Syed M. Assad, Jing Yan Haw +3
We cast the problem of illuminating an object in a noisy environment into a communication protocol. A probe is sent into the environment, and the presence or absence of the object…
Quantum homomorphic encryption from quantum codes
Yingkai Ouyang, Si-Hui Tan, Joseph Fitzsimons
The recent discovery of fully-homomorphic classical encryption schemes has had a dramatic effect on the direction of modern cryptography. Such schemes, however, implicitly rely on…
A quantum approach to homomorphic encryption
Si-Hui Tan, Joshua A. Kettlewell, Yingkai Ouyang +2
Encryption schemes often derive their power from the properties of the underlying algebra on the symbols used. Inspired by group theoretic tools, we use the centralizer of a subgro…
Generalized multi-photon quantum interference

Non-classical interference of photons lies at the heart of optical quantum information processing. This effect is exploited in universal quantum gates as well as in purpose-built q…
