In quantum computation every unitary operation can be decomposed into quantum circuits-a series of single-qubit rotations and a single type entangling two-qubit gates, such as controlled-NOT (CNOT) gates. Two measures are important when judging the complexity of the circuit: the total number of ...
Electronic ground state energy (Hartree): -8.921712043375116 Nuclear repulsion energy (Hartree): 1.05835442184 Total ground state energy (Hartree): -7.863357621535116 可能是线路参数过多导致的优化困难,于是尝试采用另一种名为EfficientSU2的HEA from qiskit.circuit.library import EfficientSU2 ansatz = EfficientSU...
VQE 中的 quantum circuit ansatz 指的就是关于|\psi(\theta)\rangle=U(\theta)|\psi_0\rangle中U(\theta)的一些先验的假设。其实就是在猜一种合适的 trial state 形式。 VQE ansatz 一般分为两类:problem-inspired ansatz 和 hardware efficient ansatz,分别从 问题背景 和 硬件条件 出发。 1 Problem-inspi...

{3}n)\), demonstrating the potential quantum advantage. Kindly note that this complexity involves neuron computation only. In addition to neuron computation, it also needs the quantum state-preparation, which can be conducted efficiently with the help of quantum random access memory (for details, ...
circuit = QuantumCircuit(2) vector = [0.124, -0.124, 0.124, 0.124] circuit.initialize(vector) In this way I encode my vector as amplitudes of the Qubits. But now I need to parameterize this (the vector is not fixed). The problem is that the "initialize" function doesn't accept paramete...
Exploiting these resources requires phase-stable quantum circuitries5,6 delivering key operations, such as entanglement generation, quantum state manipulation and detection7. In this regard, quantum walks (QWs)8,9,10 have proven to be a promising framework for search11 and universal quantum computing...
better GKP state preparation schemes have been theoretically proposed [Royer et al., Phys. Rev. Lett. 125, 260509 (2020)], so there is a good chance of improving upon the previously achieved GKP squeezing of 9.5 dB. Another key result of our paper is that the 12-...
In Qiskit, this core element is represented by theQuantumCircuitclass. Below is an example of a quantum circuit that makes a three-qubit GHZ state defined as: ∣ψ⟩=(∣000⟩+∣111⟩)/2|\psi\rangle = \left(|000\rangle+|111\rangle\right)/\sqrt{2}∣ψ⟩=(∣000⟩+∣111⟩...
