Efficient Qubit Measurement with a Nonreciprocal Microwave Amplifier.
F. Lecocq, L. Ranzani, G. Peterson +5 more·Sep 18, 2020
The act of observing a quantum object fundamentally perturbs its state, resulting in a random walk toward an eigenstate of the measurement operator. Ideally, the measurement is responsible for all dephasing of the quantum state. In practice, imperfec...
Information- and Coding-Theoretic Analysis of the RLWE/MLWE Channel
Georg Maringer, S. Puchinger, A. Wachter-Zeh·Sep 18, 2020
Several cryptosystems based on the Ring Learning with Errors (RLWE) problem have been proposed within the NIST post-quantum cryptography standardization process, e.g., NewHope. Furthermore, there are systems like Kyber which are based on the closely ...
ACSS-q: Algorithmic complexity for short strings via quantum accelerated approach
A. Sarkar, K. Bertels·Sep 18, 2020
In this research we present a quantum circuit for estimating algorithmic complexity using the coding theorem method. This accelerates inferring algorithmic structure in data for discovering causal generative models. The computation model is restricte...
A polynomial size model with implicit SWAP gate counting for exact qubit reordering
J. Mulderij, K. Aardal, I. Chiscop +1 more·Sep 18, 2020
Due to the physics behind quantum computing, quantum circuit designers must adhere to the constraints posed by the limited interaction distance of qubits. Existing circuits need therefore to be modified via the insertion of SWAP gates, which alter th...
Quantum search with prior knowledge
Xiaoyu He, Jialin Zhang, Xiaoming Sun·Sep 18, 2020
The combination of contextual side information and search is a powerful paradigm in the scope of artificial intelligence. The prior knowledge enables the identification of possible solutions but may be imperfect. Contextual information can arise natu...
Weakly measured while loops: peeking at quantum states
Pablo Andrés-Martínez, C. Heunen·Sep 18, 2020
A while loop tests a termination condition on every iteration. On a quantum computer, such measurements perturb the evolution of the algorithm. We define a while loop primitive using weak measurements, offering a trade-off between the perturbation ca...
Coordinated inference, holographic neural networks, and quantum error correction
A. Patrascu·Sep 17, 2020
Coordinated inference problems are being introduced as a basis for a neural network representation of the locality problem in the holographic bulk. It is argued that a type of problem originating in the ‘prisoners and hats’ dilemma involves non-local...
Improved Quantum Boosting
A. Izdebski, R. D. Wolf·Sep 17, 2020
Boosting is a general method to convert a weak learner (which generates hypotheses that are just slightly better than random) into a strong learner (which generates hypotheses that are much better than random). Recently, Arunachalam and Maity gave th...
Error-protected qubits in a silicon photonic chip
C. Vigliar, S. Paesani, Yunhong Ding +8 more·Sep 17, 2020
General-purpose quantum computers can, in principle, entangle a number of noisy physical qubits to realize composite qubits protected against errors. Architectures for measurement-based quantum computing intrinsically support error-protected qubits a...
Fast and robust quantum state tomography from few basis measurements
F. Brandão, R. Kueng, Daniel Stilck França·Sep 17, 2020
Quantum state tomography is a powerful, but resource-intensive, general solution for numerous quantum information processing tasks. This motivates the design of robust tomography procedures that use relevant resources as sparingly as possible. Import...
Exploring a Double Full-Stack Communications-Enabled Architecture for Multi-Core Quantum Computers
Santiago Rodrigo, S. Abadal, E. Alarcón +1 more·Sep 17, 2020
Being a very promising technology, with impressive advances in the recent years, it is still unclear how quantum computing will scale to satisfy the requirements of its most powerful applications. Although continued progress in the fabrication and co...
Practical Quantum Computing: The value of local computation.
James R. Cruise, Neil I. Gillespie, B. Reid·Sep 17, 2020
As we enter the era of useful quantum computers we need to better understand the limitations of classical support hardware, and develop mitigation techniques to ensure effective qubit utilisation. In this paper we discuss three key bottlenecks in nea...
The quest and hope of Majorana zero modes in topological superconductor for fault-tolerant quantum computing: An introductory overview
N. R. Ayukaryana, M. H. Fauzi, E. Hasdeo·Sep 16, 2020
Ettore Majorana, in his short life, unintendedly has uncovered the most profound problem in quantum computation by his discovery of Majorana fermion, a particle which is its own anti-particle. Owing to its non-Abelian exchange statistics, Majorana fe...
Benchmarking quantum state transfer on quantum devices
Yi-Te Huang, Jhen-Dong Lin, Huan-Yu Ku +1 more·Sep 16, 2020
Quantum state transfer (QST) provides a method to send arbitrary quantum states from one system to another. Such a concept is crucial for transmitting quantum information into the quantum memory, quantum processor, and quantum network. The standard c...
Extended flag gadgets for low-overhead circuit verification
D. Debroy, K. Brown·Sep 16, 2020
Flag verification techniques are useful in quantum error correction for detecting critical faults. Here we present an application of flag-verification techniques for improving postselected performance of near-term algorithms. We extend the definition...
