Detection of quantum critical points by a probe qubit
Jingfu Zhang, Xinhua Peng, Nageswaran Rajendran +1
Quantum phase transitions occur when the ground state of a quantum system undergoes a qualitative change when an external control parameter reaches a critical value. Here, we demon…
Iterative quantum state transfer along a chain of nuclear spin qubits
Jingfu Zhang, Nageswaran Rajendran, Xinhua Peng +1
Transferring quantum information between two qubits is a basic requirement for many applications in quantum communication and quantum information processing. In the iterative quant…
Effect of system level structure and spectral distribution of the environment on the decoherence rate
Jingfu Zhang, Xinhua Peng, Nageswaran Rajendran +1
Minimizing the effect of decoherence on a quantum register must be a central part of any strategy to realize scalable quantum information processing. Apart from the strength of the…
Factorizing Numbers with the Gauss Sum Technique: NMR Implementations
T. S. Mahesh, Nageswaran Rajendran, Xinhua Peng +1
Several physics-based algorithms for factorizing large number were recently published. A notable recent one by Schleich et al. uses Gauss sums for distinguishing between factors an…
