UROP, Francisca Vasconcelos, interviewed four MIT quantum computing and information faculty – William Oliver, Dirk Englund, Isaac Chuang, and Aram Harrow – for the MIT Undergraduate Research Journal (MURJ). The article, “Quantum Computing @ MIT: The Past, Present, and Future of the Second Revolution in Computing,” provides a high-level overview of the history of the field, current research challenges, and future prospects of the technology.

This review presents an academic perspective in tandem with the recent media hype surrounding quantum computing, specifically highlighting progress being made at MIT. An abridged version was published in the MURJ Volume 38 publication.

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 Quantum Economic Development Consortium (QED-C) hosted a two-day workshop, the QED-C Workshop on Materials for Superconducting Qubits.

Will kicked off the workshop with a talk titled “Introduction to Superconducting Qubits.”

The workshop’s goal is to create connections between the material science and the superconducting qubit communities in order to better understand defects, facilitate the discovery of new materials, and design and fabricate more controllable quantum systems.

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

He presented his work on inverse design of superconducting circuits at the Catalan Institute of Nanoscience and Nanotechnology and the University of Barcelona. With Pol Forn-Díaz (see picture below), he discussed new circuits for quantum annealing. He also helped with  an experiment that is set to demonstrate the first quantum control of a superconducting qubit in the Mediterranean area.

For more information on Tim’s visit, see the blog post written by the QUANTIC about his visit.[/vc_column_text][vc_single_image image=”1340″ img_size=”full” add_caption=”yes”][vc_text_separator title=”October 4, 2018″ border_width=”3″][vc_column_text]MIT.nano is unveiled | Cambridge, MA

Will gave a keynote address on quantum computing at the MIT.nano launch. His talk was followed by a panel of industry and research leaders, including Bogdan Mihaila (NSF),  Mark Ritter (IBM), and Eric Dauler (MIT Lincoln Lab). Isaac Chuang, an MIT professor of EECS and the Senior Associate Dean of Digital Learning, moderated the panel.

MIT.nano is MIT’s new fabrication facility, and quantum information science represents one of the major thrusts at the Institute that will be enabled by these new facilities.

Please give a warm welcome to Jochen Braumüller, a new postdoc in the group!

After receiving his Ph.D. from Karlsruhe Institute of Technology in 2017 and completing a short postdoc there, he joined MIT to work on novel qubit architectures and alternative approaches to protect and encode quantum information that potentially allow for a more efficient scaling of quantum hardware.[/vc_column_text][vc_text_separator title=”May 25, 2018″ border_width=”3″][vc_column_text]Philip takes his next steps | Cambridge, MA

Best of luck to postdoc, Philip Krantz, as he moves onto a new role as project coordinator at the Wallenberg Centre for Quantum Technology (WACQT) at Chalmers University, beginning June 1^st!

The group gathered at Meadhall a few weeks prior to enjoy a farewell dinner celebrating Philip’s three years at MIT.

It’s been a joy having him in the group twice: once as a graduate student (2013) and then again as a postdoc (2015-2018). Thank you, Philip, for your mentorship, dedication, and scientific contributions. He will surely be missed![/vc_column_text][vc_text_separator title=”May 2, 2018″ border_width=”3″][vc_column_text]Fei and Dan publish a paper | Cambridge, MA
