SUMMARY:[Seminar] : Quantum control of spin qubits with classical nanomagnets
DESCRIPTION:Speaker: Prof. Jayasimha Atulasimha\, Professor\, Mechanical and Nuclear Engineering\, \nVirginia Commonwealth University Richmond\, Virginia\, USA. \n\nTitle: "Quantum control of spin qubits with classical nanomagnets".\n\nDate: Friday\, 31st July 2026 - Time: 4 PM\n\nHi-Tea & Coffee: 5 PM\n\nVenue: CeNSE Seminar Hall\n\nAbstract:\nOur group has demonstrated energy-efficient electrical control of nanoscale magnetisation \ndynamics using strain-mediated voltage control [1]\, and voltage control of magnetic anisotropy \n[2] in nanomagnets and skyrmions\, respectively. These have found applications in implementing \nnon-volatile memory [1\,2] and neuromorphic computing [3]. However\, such nanomagnets can generate \nhighly confined microwaves to control the quantum state of proximally located spin qubits.\n\nThis talk will discuss the use of microwaves generated by voltage-controlled magnetisation dynamics \nin nanomagnets [4]to implement single-qubit quantum gates with fidelities approaching state-of-the-art \n[4] in a scalable manner. We will also discuss recent experiment work demonstrating coherent quantum \ncontrol of a single nitrogen vacancy (NV) centre in diamond with microwave fields generated from\nproximally located shape-anisotropic nanomagnets of lateral dimensions down to 200 nm x 180 nm\, \ndriven remotely by surface acoustic wave (SAW) excitation [5]. Specifically\, high-contrast Rabi \noscillations have been demonstrated. Additionally\, we report relaxometry using microwave pulses \ngenerated by such proximally located nanomagnets that can be orders of magnitude more efficient \nthan using a conventional antenna [5].  Such localised and energy-efficient control has potential \nto lead to scalable quantum computing and sensing with NV defects in diamond and other spin qubits.\n\nFinally\, we have shown that it is possible to control of spin qubits using SOT-driven nanomagnets [6] \nthat are at least an order of magnitude more efficient and have higher gate speeds than conventional \nElectron Spin Resonance (ESR) driven spin qubits\, while they have gate speeds comparable to Electron \nDipole Spin Resonance (EDSR) driven spin qubits with an order of magnitude higher coherence times [6].\n\nReferences\n\n[1] Nano Letters\, 16\, 1069\, 2016; ACS Applied Materials & Interfaces\, 17\, 48\, 65946\, 2025.\n\n[2] Nature Electronics 3\, 539\, 2020.\n\n[3] Neuromorph.

SUMMARY:[Seminar] : Graphene-Enabled Advances in Flexible Electronics and Bioelectronics
DESCRIPTION:Speaker: Dr. Prashant Hanumant Narute\, Former Postdoctoral Research Associate\, \nDepartment of Biomedical Engineering\, University of Massachusetts\, USA.\n\nTitle: "Graphene-Enabled Advances in Flexible Electronics and Bioelectronics"\n\nDate: Thursday\, 6th August 2026 - Time: 4 PM\n\nHi-Tea & Coffee: 5 PM\n\nVenue: CeNSE Seminar Hall\n\nAbstract:\n\nGraphene\, celebrated for its exceptional mechanical\, electrical\, and biocompatible properties\, \nis driving the next generation of flexible electronics and wearable healthcare technologies. \nThis talk will highlight recent advances in engineering graphene from fundamental materials science \nto practical biomedical applications. The first part will focus on polymer-supported graphene and \nstrategies to overcome key challenges in fabrication\, transfer\, and electromechanical reliability\, \nwith the overarching goal of translating graphene-based flexible and stretchable electronics from the \nlaboratory to real-world technologies. The second part will explore graphene's emerging role in \nbioelectronics\, where its ultrathin\, skin-conformal\, self-adhesive\, and biocompatible nature enables \nseamless integration with the human body. I will present our work on graphene electronic tattoos \n(GETs) – ultrathin\, imperceptible devices for continuous\, non-invasive physiological monitoring – and \ndiscuss their potential for next-generation personalized healthcare. Together\, these advances \ndemonstrate how graphene is bridging engineering and medicine to create transformative technologies \nfor the future.\n\nBiography:\n\nDr. Prashant Narute was a Postdoctoral Research Associate at the University of Massachusetts (UMass)\, \nAmherst\, USA\, specializing in graphene technology. He pursued BE in Chemical Engineering from \nShivaji University and his MTech in Chemical Technology from LIT Nagpur in collaboration with \nCSIR-IICT\, Hyderabad. He pursued his Ph.D. in Nano Science from the University of Science and \nTechnology\, Republic of Korea. His doctoral research was focused on large-area polymer-supported \ngraphene and wrinkled-graphene for flexible electronics and nanomechanics of 2D materials using \nin-situ SEM technique. After Ph.D.\, Dr. Prashant served as a Postdoctoral Researcher at the NUS\, \nSingapore\, and recently at UMass Amherst was focused on graphene-based bioelectronics\, including \ngraphene electronic tattoos (GET) and graphene-integrated devices for physiological signals \nmonitoring and bioelectronics applications. Dr. Prashant was honoured with the "Outstanding Research \nStudent – 2022" for conducting impactful research on graphene during his Ph.D. His research \ncontributions have been published through high-impact publications\, patents\, news articles\, \nand awards. Outside of his academic endeavours\, he enjoys badminton\, swimming\, and travelling.\n\n\nHost Faculty:  Prof. Manoj Varma
