Jochen and Leon submit to arXiv | Cambridge, MA
Postdoctoral associate Jochen Braumüller and graduate student Leon Ding submitted their work on 1/f flux noise to the arXiv, titled “Characterizing and optimizing qubit coherence based on SQUID geometry.”
In their paper, Jochen and Leon investigate the noise properties of more than 50 flux qubits with varying designs of their SQUID loops and observe quantitative agreement of their data with a microscopic model for magnetic flux noise. These results provide a guide for minimizing flux noise in future quantum circuits.

EQuS submits six papers to arXiv | Cambridge, MA
Congratulations to the lead authors and co-authors from EQuS who recently submitted papers to the arXiv during December and January!
Uwe von Luepke’s paper, “Two-qubit spectroscopy of spatiotemporally correlated quantum noise in superconducting qubits,” discusses noise spectroscopy of spatiotemporally correlated noise in two qubits. While error detection and correction protocols exist, most rely on an uncorrelated noise assumption. To understand and address correlated noise, one first must characterize it. In this work, Uwe and co-authors experimentally validate a protocol for achieving two-qubit quantum noise spectroscopy. Uwe was a visiting student in EQuS from 2017-2018.
Graduate student, Bharath Kannan’s work, “Waveguide quantum electrodynamics with giant superconducting artificial atoms,” realizes “giant atoms” by coupling transmon qubits to multiple, well-separated locations along a waveguide. When modeling light-matter interactions, atoms are typically treated as small point-like objects. The paper probes the physics of the giant-atom regime of waveguide quantum electrodynamics (wQED) and shows that this architecture can be applied for quantum simulations and non-classical photon generation for quantum communication protocols.
Ana Laura Gramajo’s paper, “Quantum simulation of coherent backscattering in a system of superconducting qubits,” discusses the implementation of a quantum emulator of weak localization (WL) and universal conductance fluctuations (UCF) using coherent scattering at an avoided crossing in a system of two coupled superconducting qubits. The scattering events are controllably implemented as coherent Landau-Zener transitions by driving the two-qubit system multiple times through an avoided crossing. While a priori there is not a direct connection between driven superconducting qubits and mesoscopic disordered electronic systems, the results demonstrate how a well-controlled driven qubit system can be used to study complex effects in mesoscopic physics. Ana was a visiting student in EQuS during 2018.
Postdoctoral Associate Morten Kjaergaard and Lincoln Laboratory Research Scientist Mollie Kimchi-Schwartz submitted their demonstration of a quantum algorithm, entitled “A quantum instruction set implemented on a superconducting quantum processor.” In their paper, they use two superconducting qubits to make the first experimental demonstration of the Density Matrix Exponentiation algorithm. Their experiment shows for the first time how quantum states can act as a quantum instruction set to program a quantum computer.
Postdoctoral Associate Antti Vepsäläinen and graduate student Amir Karamlou submitted their work, entitled “Impact of ionizing radiation on superconducting qubit coherence.” In collaboration with the group of MIT Physics Professor Joe Formaggio, researchers at Pacific Northwest National Laboratory (PNNL), and MIT Lincoln Laboratory researchers, Antti and Amir characterized the impact of ionizing radiation from the cosmic rays and environmental nuclear decay on superconducting qubit coherence. They also showed that using a lead shield can improve coherence times by reducing the flux of radiation. In order to beat down the noise, EQuS researchers performed a Dicke radiometry “lock-in” experiment, raising and lower a two-ton lead shield on a 10-minute period for 4 days(!)
Graduate student Tim Menke, who holds a joint appointment at MIT and Harvard, also submitted his paper entitled “Automated discovery of superconducting circuits and its application to 4-local coupler design.” In this work, Tim used an optimization algorithm to design a superconducting qubit circuit based on a generalized network of circuit elements and a predefined cost function.

The QED-C was developed under the National Quantum Initiative. Its purpose is three-fold:
- To support enabling technology R&D: e.g. quantum device components, instrumentation, and performance standards
- To facilitate industry coordination and interaction with government agencies
- To provide the government with a collective industry voice in guiding R&D investment priorities and quantum workforce issues
