Abstract

1.    Reliability Challenges and Solutions for Emerging Non-Volatile Memories

Emerging non-volatile memory technologies are attracting a lot of attention in order to enable new computing paradigms and provide more desirable computer memories. However the introduction of new technologies has always been accompanied by challenges for delivering high quality and reliable products. This talk overviews the main characteristics of popular emerging non-volatile memories and discusses their Reliability concerns and solutions. Moreover, their future trends and challenges will be addressed.

 2.    Cryogenic CMOS LNA for RF readout of spin qubits:

Quantum computation is bringing excitement and motivation into the scientific community to build a practical quantum computer. This would enable the solution of problems today intractable, thanks to the exponential decrease in the required number of operations with respect to a classical computer. Nevertheless, this extraordinary computer needs support from a classical computer to perform specific side tasks, such as quantum error correction, control and post-processing of the information where classical electronics is more efficient. Further, to enable the scalability of quantum computers reducing the huge amount of interconnections that are nowadays needed to perform quantum computation, classical electronics must be placed close to the quantum processor at cryogenic temperatures (4 K).

To address this, firstly a compact model for simulation of CMOS at cryogenic temperature is proposed and secondly a CMOS Low-Noise Amplifier (LNA) is designed and tested at liquid Helium temperature (4 K). The cryoLNA is the first in this technology and will be employed in the RF electronic readout of spin qubit, replacing the existing discrete amplifier used in state-of-the-art experimental setup. The functionality of the CMOS LNA at deep cryogenic temperatures demonstrates the effectiveness of cryoCMOS and makes a first step towards the realization of integrated and scalable quantum computers.

Bio

Peyman Pouyan has received his PhD degree in electronic engineering, from the Polytechnic University of Catalonia (UPC), in 2015. He has 20 international publication works and is currently a postdoc researcher at computer engineering lab. His main research interests are semiconductor reliability and emerging non-volatile memories.

Rosario Incandela has just been appointed as a PhD in Advanced Quantum Architecture (AQUA), TU Delft, under the supervision of E. Charbon and F. Sebastiano. He graduated on the 28th of October 2016 on the topic : ‘Cryogenic CMOS LNA for RF readout of spin qubits’. His PhD research will focus on the design of cryogenic CMOS circuits for the readout of spin qubits, towards the realization of a practical quantum computer.
