It turns out, however, that as a consequence of the defining dynamical equations of Bohmian mechanics, when a system has wave function 蠄its configuration is typically random, with probability density 蟻given by |蠄|2, the quantum equilibrium distribution. It also turns out that the entire ...
we recover the observable in the error-free circuit using an error mitigation formula, which is a function of observables directly measured with noisy circuits. Many such formulas are inspired by our knowledge of quantum physics, such as error extrapolation6,7,31...
Many such formulas are inspired by our knowledge of quantum physics, such as error extrapolation6,7,31,32, probabilistic error cancellation7,8 and virtual distillation13,14,33,34,35. Throughout this work, when a concrete error mitigation formula is needed for analysis, we take the three ...

When m=0 the two equations coincide. It is clear in these formulas that the propagator kernel is radially symmetric, and that all information from the initial data travels at finite speed. Both equations also possess a well-known dispersive property that |u(x,t)|≤C|t|−1/2 provided th...
We give a quantum algorithm for evaluating a class of boolean formulas (such as NAND trees and 3-majority trees) on a restricted set of inputs. Due to the structure of the allowed inputs, our algorithm can evaluate a depth n tree using O(n2+logω) queries, where ω is ind...
Current battery R&D relies on long cycles of experimentation and computational simulation. Quantum computing offers the ability to simulate every element of the battery chemistry in a virtual experiment at the atomic level. Variables such as electrode materials, electrolyte formulas, binders and separators...
For a wave function Ψ(r,t), an expansion into an orthonormalized function system can be pursued (for simplicity, index m is omitted in the following equations): Fnl(r)=Ylm(r^) fnl(r)r , fnl(r)=λn!(n+2l+2)! (λr)l+1 e−λr2 Ln2l+2(λr) (23) with orthonormalization...
and the form of the recursive laws for the structure constants of rational curves of arbitrary degree. Our recursive formulas should yield the coefficients of the hypergeometric series used in the mirror calculation. Assuming the validity of the conjectures we find the recursive laws for rational ...
The total action of the extended theory is still (4.8), and satisfies the master equations (4.9) and (4.10). Moreover, (SKcloudi , Stot) = 0 (8.4) for every i. It is always possible to build gauge invariant functions with two cloud fields. For example, the functions ζ1μi (x)...
