Taking extreme field sensing from the lab to the real world. The first non-cryogenic alternative to superconducting magnetometers. Our optical magnetometers are extremely sensitive, easy to use and provide unprecedented flexibility. © 2025 QuSpin. All …

The QuSpin Total-Field Magnetometer (QTFM) is a compact, high-sensitivity hybrid scalar + three-axis vector atomic magnetometer for geophysical applications. It is extremely accurate, stable, and can resolve minute field changes.

The QuSpin Zero-Field Magnetometer (QZFM) is an ultra-sensitive vector magnetometer that operates in low field environments. It is among the most sensitive magnetic detectors with performance rivaling superconducting technologies.

QuSpin is an open-source Python package for exact diagonalization and quantum dynamics of arbitrary boson, fermion and spin many-body systems. QuSpin supports the use of various (user-defined) symmetries for one and higher-dimensional lattice systems, (imaginary) time evolution following arbitrary user-specified driving protocols, constrained ...

QuSpin´s objective is to develop the basic science that uses quantum entities such as the electron spin as information carriers in radically different ways. We aim at groundbreaking basic research that is crucial to the development of fast, high-capacity, material systems and tools for smaller and more power-efficient electronic devices.

近日，由量旋科技（SpinQ）、香港科技大学、深圳大学、粤港澳大湾区量子科学中心的专家，联合发布的一项最新研究成果，被国际物理学顶级期刊《Physical Review Letters》 (PRL，物理评论快报) 收录。 两会热词！ 政府工作报告频频点名“量子科技”，政策升级加速未来产业布局. “量子科技”再次成为政府工作报告和代表委员热议的关键词之一。 引入4台量旋双子座Mini Pro量子计算机，成为南欧首个规模化部署量子计算教学设备的高校。 项金根认为，尽管中美在量子科技的 …

安装完成了 QuSpin，下面我们可以开始使用了，第一个例子，我们来研究一下 SSH模型，这个模型可以给出两种不同的拓扑相（topological phase），可以由卷绕数来判断，模型有以下的形式，我们给出著名的 Su-Schrieffer-Heeger (SSH)模型的 哈密顿量 的一般形式， \begin {equation}\label {} \hat {H}=\sum_ {i}t_1\hat {c}_ {A,i}^ {\dagger}\hat {c}_ {B,i}+t_2\hat {c}_ {A,i+1}^ {\dagger}\hat {c}_ {B,i}+h.c. \end {equation}

QuSpin需要 Python3.7 的版本，详细的内容可以参考（最近更新了，有空更新一下！ 首先，我们需要一个anaconda或者miniconda（现在 anaconda 官网已经进不去了，早几个月都还可以当时还下了一个 exe文件，但是我给删掉了~~哭哭~~），所以可以选择miniconda（如果anaconda又可以进的话那就两个任选一个安装就可以了，anaconda相对会大一些，下面这个网站是anaconda的）

The QuSpin Total-Field Magnetometer (QTFM) is a compact, high-sensitivity scalar magnetometer. It can operate in Earth’s field, is extremely accurate and can resolve very minute field changes. Our sensor is among the highest performing in the world.
