EQuS members teach Intro to Quantum class | Cambridge, MA

New to quantum? This IAP, MIT will offer an “Introduction to Quantum Computing” course taught by grad student, Amir Karamlou, and UROPs, Francisca Vasconcelos and Megan Yamoah.

Within the first three weeks, the course will cover some fundamental quantum mechanics, survey quantum circuits, as well as introduce important quantum algorithms. In the fourth and final week, they will survey advanced topics, such as quantum error correction and quantum communication, as well as applications to fields ranging from machine learning to chemistry.

For more information, contact Amir Karamlou at karamlou (at) mit.edu.

EQuS celebrates at second annual holiday party | Cambridge, MA

Friends, families, and members of EQuS gathered to celebrate the end of the year at the annual holiday party. Dinner, dessert, and drinks were served at Flour, featuring a few special treats made by EQuS’ own.

In addition to wrapping up another year of hard work, challenges, and successes, we also recognized postdoc Daniel Campbell, as he moves onto his next chapter as a quantum scientist at Booz Allen Hamilton in January. You will be missed, Dan! Thank you for the scientific contributions, mentorship, and kindness you’ve been bringing to this group since joining in 2015.

Looking forward to another year or learning and growing in EQuS!

NASEM releases the consensus study report on quantum computing | Washington, DC

The National Academies of Science, Engineering, and Medicine (NASEM) released a report providing an independent assessment of the feasibility and implications of creating a functional quantum computer capable of addressing real-world problems.

Will was a member of the committee led by Mark Horowitz (Stanford University) that created the report over the course of 18 months.

The study focuses on the technical risks associated with developing a quantum computer, the implications of having one, the future of public key cryptography, and the costs and benefits from a national security perspective.

DOE BES awards sponsored research grant | Cambridge, MA

The EQuS group has been selected by The Department of Energy (DOE), Basic Energy Sciences (BES), to perform sponsored research as part of the Materials and Chemical Sciences Research for Quantum Information Science program.

The selected proposal, titled “High-Coherence Multilayer Superconducting Structures for Large-Scale Qubit Integration and Photonic Transduction,” is led by Lawrence Berkeley National Laboratory (LBNL) and includes co-PIs from UC Berkeley and the EQuS group at MIT.

The three-year program will focus on the development of novel materials, fabrication, and design to enable high-coherence qubits, as well as the generation and detection of non-classical light.

Tim visits and speaks at QUANTIC | Barcelona, Spain

Grad student Tim Menke visited the QUANTIC group, an exciting quantum computing joint venture of several institutes in Barcelona.

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.
