Parasitic-free gate: A protected switch between idle and entangled states

We propose a protected 2-qubit gate composed of two sub-gates that switches between idling and entangling modes. These sub-gates are separated by a large energy barrier. In superconducting circuits, this gate is derived by harnessing microwave driving and coupling modulation. The idle mode decouples qubits and leaves them with highly localized wave functions. The entangled mode, however, makes them interact in absence of the adversarial ZZ interactions. Our theoretical results show that this gate is a promising way to switch on and off a fast and high fidelity 2-qubit interaction. Read further details here

PhD position in my group

The theory groups at the Institute for Quantum Information of the Jülich-Aachen Research Alliance (JARA) are looking for a highly motivated candidate to fill a PhD position over the next few months. The doctoral project will focus on theoretical studies of physical implementations of quantum information processing, such as superconducting qubits, and enabling quantum technologies. The projects will be supervised by Dr. M.H. Ansari and may involve collaborations with leading experimental groups.

Master’s degree (or equivalent) in theoretical condensed matter physics or a related field and proficiency in English are required. Preference will be given to candidates with experience in quantum transport and open quantum systems, but strong candidates from other fields are encouraged to apply.

The application material should include:

• Short letter of motivation (less than a page)
• CV and transcripts
• Contact details (names and emails) of two possible referees

For further information about the group see the group webpage: https://sites.google.com/site/mansari.

To submit an application please email your documents to m.ansari@fz-juelich.de. Review of applications will start immediately and continue until all the position is filled.

New Physics talk

Recently I was invited to give a Quantum Information Seminar at Physics department of Syarcuse University, NY. There was a broad audience from high energy physics to cosmology, quantum chemistry, gravity and black holes and quantum computation, both experimentalists and theorists. My talk was about a new correspondence we found recently between physics and information. Below you can find my abstract, for questions contact me.

New Physics from Quantum Information Theory by Dr. Mohammad Ansari

Jan 17, 2019 at 11:00 AM - 12:00 PM

Room: 202 Physics Bldg.

In quantum physics physical quantities are linear in density matrix, e.g. energy, current, spin, etc. However, this is not the case in quantum information theory as  informational measures are nonlinear functions in density matrix; examples are entropy, fidelity loss, purity, etc.  Is there any way to measure information in the lab using physical quantities? This is an important question that I’ll address in this talk. I’ll present a new correspondence between entropy and physical quantities. I will  discuss how this correspondence may introduce new physics in quantum heat engines, quantum computation, black holes, etc..

Donna Strickland

The lady who taught us nonlinear optics in Waterloo during my PhD studies just received a Nobel Prize in Physics! Dr Donna Strickland is nice, honest, and down-to-earth modest, such that I  could not shamefully believe that she is better than others! She was excellent teacher also and was delivering science very well to students, and always with a taste of sweetness!

Her story of being so humble remind me of the following poem by Emily Dickinson:
I'm Nobody! Who are you?
Are you -Nobody- too?
Then there's a pair of us!
Don't tell! they'd...

The institute of Theoretical Nanoelectronics (PGI-2) concerns itself with investigating structure formation in condensed matter, starting on electronic length and time scales while bearing in mind macroscopic consequences. These studies are closely connected in diverse ways with experimental work within the institute, and also with projects in other institutes at Forschungszentrum Jülich.

The main focus of our work is placed on the electronic structure of solids, in particular with regard to their importance in information technology and cooperative phenomena in condensed matter. Research questions here concern dynamic structure formation processes together with the statistical mechanics of order and disorder processes. Special topics in the field of complex fluids deal with the structure and dynamics of soft matter.

We are looking to recruit as soon as possible a
