Superconducting microwave cavities with ultra-high Q-factors are revolutionizing the field of quantum computing, offering long coherence times exceeding 1 ms, which is critical for realizing scalable multi-qubit quantum systems with low error rates. ...
Quantum Error Correction For Dummies
Avimita Chatterjee, Koustubh Phalak, Swaroop Ghosh·Apr 18, 2023
In the current Noisy Intermediate Scale Quantum (NISQ) era of quantum computing, qubit technologies are prone to imperfections, giving rise to various errors such as gate errors, decoherence/dephasing, measurement errors, leakage, and crosstalk. Thes...
Towards Advantages of Parameterized Quantum Pulses
Zhiding Liang, Jinglei Cheng, Zhixin Song +8 more·Apr 18, 2023
The advantages of quantum pulses over quantum gates have attracted increasing attention from researchers. Quantum pulses offer benefits such as flexibility, high fidelity, scalability, and real-time tuning. However, while there are established workfl...
Exploring exotic configurations with anomalous features with deep learning: Application of classical and quantum-classical hybrid anomaly detection
Kumar Ghosh, Sumit Ghosh·Apr 17, 2023
In this article we present the application of classical and quantum-classical hybrid anomaly detection schemes to explore exotic configuration with anomalous features. We consider the Anderson model as a prototype where we define two types of anomali...
A ZX-Calculus Approach for the Construction of Graph Codes
Zipeng Wu, Song Cheng, B. Zeng·Apr 17, 2023
Quantum Error-Correcting Codes (QECCs) play a crucial role in enhancing the robustness of quantum computing and communication systems against errors. Within the realm of QECCs, stabilizer codes, and specifically graph codes, stand out for their disti...
Flow-preserving ZX-calculus Rewrite Rules for Optimisation and Obfuscation
Tommy McElvanney, Miriam Backens·Apr 17, 2023
In the one-way model of measurement-based quantum computation (MBQC), computation proceeds via measurements on a resource state. So-called flow conditions ensure that the overall computation is deterministic in a suitable sense, with Pauli flow being...
Laser Systems for High Fidelity Control and Entanglement of Neutral Atomic Qubits
C. Picken, I. Despard, A. Kelly +5 more·Apr 17, 2023
We present new photonics and electronics packages recently developed by M Squared Lasers specifically tailored for scalable neutral atom quantum computing; a high power 1064 nm system for scalable qubit number, a phase locked system for high fidelity...
Multispin Clifford codes for angular momentum errors in spin systems
Sivaprasad Omanakuttan, J. Gross·Apr 17, 2023
The physical symmetries of a system play a central role in quantum error correction. In this work we encode a qubit in a collection of systems with angular-momentum symmetry (spins), extending the tools developed in Phys. Rev. Lett. 127, 010504 for s...
A quantum advantage over classical for local max cut
Charles Carlson, Zackary Jorquera, A. Kolla +1 more·Apr 17, 2023
We compare the performance of a quantum local algorithm to a similar classical counterpart on a well-established combinatorial optimization problem LocalMaxCut. We show that a popular quantum algorithm first discovered by Farhi, Goldstone, and Gutman...
Zero sum subsequences and hidden subgroups
Muhammad Imran, G. Ivanyos·Apr 17, 2023
We propose a method for solving the hidden subgroup problem in nilpotent groups. The main idea is iteratively transforming the hidden subgroup to its images in the quotient groups by the members of a central series, eventually to its image in the com...

We propose an imaginary time equivalent of the well-established Pauli gadget primitive for Trotter-decomposed real time evolution, using mid-circuit measurements on a single ancilla qubit. Imaginary time evolution (ITE) is widely used for obtaining t...
A Quantum Computing-driven Aid for New Material Design
R. KensonWesley, Dr. Reena Monica·Apr 16, 2023
Material discovery is a phenomenon practiced since the evolution of the world. The Discovery of materials had led to significant development in varied fields such as Science, Engineering and Technology etc., It had been a slow and long-drawn process,...
Leakage Benchmarking for Universal Gate Sets
Bujiao Wu, Xiaoyang Wang, Xiao Yuan +2 more·Apr 16, 2023
Errors are common issues in quantum computing platforms, among which leakage is one of the most-challenging to address. This is because leakage, i.e., the loss of information stored in the computational subspace to undesired subspaces in a larger Hil...
