meaning that QLanczos is potentially noise resilient. Combined with fast convergence the algorithm has a few advantages that make it useful for quantum computation of the ground and excited-state energies of many-body systems. Since our QLanczos results are in good agreement with the ...
the number of energy levels. For example, in the excitation system shown inFig. 1.2a, the quantav41,v42,v43,v32,v31andv21can form during absorption of a single quantumv41. In these conditions, the introduction of the concept of the quantum yield has no special meaning and is not used...
She held postdoctoral appointments in bioengineering at Stanford University and in chemistry at the University of California, Berkeley. Two months before the pandemic, she joined the University of California, Los Angeles, where she leads the Quantum Biology Tech (QuBiT) Lab. *** The author thanks...
With the rapid development of high-performance computers and more efficient quantum chemical (QC) methods, QC descriptors with accurate characterization of electronic structures and clear mathematical meaning are essential for the development of QSAR models. This paper systematically summarizes the advantages...
For instance, atoms and other particles can exist in states of flux known as superpositions, where they can seemingly each spin in opposite directions simultaneously, and they can also get entangled - meaning they can influence each other instantaneously no matter how far apart they are separated....
There is still some polynomial scaling with N, which is a result of the increased resolution meaning that electrons can be closer together. If we were to consider constant resolution (as in refs 8,9,10), our complexity would actually be polylogarithmic in N, representing an exponential ...
‘on average’ with the environment, and spreads information about its classical states into the surroundings. Since you are a macroscopically large human, any measurement you do will induce this sort of equilibration to happen, meaning you will only ever have access to the classical information ...
quantum chemistry, optimization problems, and quantum machine learning, many new kinds of quantum algorithms have been recently developed such as Variational Quantum Eigensolver (VQE)23,24,25,26,27, Quantum Approximate Optimization Algorithm (QAOA)27,28,29,30,31,32,33, and hybrid quantum-classical...
