About me

I’m a Ph.D. student at the Systems Research Group, Technical University of Munich (TUM), supervised by Prof. Pramod Bhatotia. My research interests lie in the field of systems software for quantum computing, i.e., I bring systems abstractions and mechanisms into quantum computing for improved programmability, performance, and scalability.

In particular, I focus on compiler and OS mechanisms that address the low fidelity, heterogeneity, under-utilization, and significant queuing times of quantum resources. To achieve this, I design systems that leverage quantum error mitigation, circuit cutting and knitting, multi-programming, and hybrid quantum-classical resource estimation and scheduling.

Previously, I worked in the distributed systems area, specifically in distributed shared logs, hardware-assisted replication protocols, and the implementation of fast reads in asynchronous replication protocols.

Before joining TUM, I graduated from the Computer Science Department, University of Crete, Greece, where I worked on highly parallel data structures and cloud scheduling.

Please call me Manos. Emmanouil sounds awkwardly official.

Hobbies & Interests

I really love cinema (I have watched more than 800 films), so follow me on Letterboxd if you have an account ;) Letterboxd profile. I also like photography, focusing on landscapes, nature, and architecture. Despite being a computer scientist, I am pretty active: I enjoy hiking (I’m proud of my recent achievement of hiking the Andes, a 4000->5000 meters altitude hike), swimming, lifting weights in the gym, and running.
