Exchange-Coupled Spins for Robust High-Temperature Qubits
Aniruddha Chakraborty, Md. Fahim F. Chowdhury, Mohamad Niknam +2
We show that Heisenberg exchange interactions between the neighboring spins comprising an ensemble spin qubit (E-qubit) can act as an intrinsic error mitigator, increasing gate fid…
Energy efficient coherent quantum control of nitrogen vacancy (NV) spin with nanoscale magnets
Md Fahim F Chowdhury, Adi Jung, Lea La Spina +3
We investigate coherent quantum control of a nitrogen vacancy (NV) center in diamond with microwave fields generated from a nanoscale magnet that is proximal to the NV center. Our…
Proximal quantum control of spin and spin ensemble with highly localized control field from skyrmions
Md Fahim F Chowdhury, Mohamad Niknam, Md Mahadi Rajib +2
Selective control of individual spin qubits is needed for scalable quantum computing based on spin states. Achieving high-fidelity in both single and two-qubit gates, essential com…
Quantum Control of Spin Qubits Using Nanomagnets
Mohamad Niknam, Md Fahim F. Chowdhury, Md Mahadi Rajib +5
Single-qubit gates are essential components of a universal quantum computer. Without selective addressing of individual qubits, scalable implementation of quantum algorithms is not…
Skyrmion based energy efficient straintronic physical reservoir computing
Md Mahadi Rajib, Walid Al Misba, Md. Fahim F. Chowdhury +2
Physical Reservoir Computing (PRC) is an unconventional computing paradigm, which exploits nonlinear dynamics of reservoir blocks to perform recognition and classification tasks. H…
Focused Surface Acoustic Wave induced nano-oscillator based reservoir computing
Md. Fahim F. Chowdhury, Walid Al Misba, Md Mahadi Rajib +4
We demonstrate using micromagnetic simulations that a nanomagnet array excited by Surface Acoustic Waves (SAWs) can work as a reservoir that can classify sine and square waves with…
Passive frustrated nanomagnet reservoir computing
Alexander J. Edwards, Dhritiman Bhattacharya, Peng Zhou +10
Reservoir computing (RC) has received recent interest because reservoir weights do not need to be trained, enabling extremely low-resource consumption implementations, which could…
