量子计算机的工作方式并不相同，这给开发者带来了问题。为一台机器编写的代码，在另一台机器上运行前可能需要重写。Postquant Labs希望改变这一现状。
Quantum computers don’t all work the same way, and that creates a problem for developers. Code written for one machine may need to be rewritten before it can run on another. Postquant Labs wants to change that.
这家美国初创公司推出了Quip虚拟机（QVM），这是一个软件层，让开发者只需编写一次代码，即可在不同类型的量子计算机和传统机器上运行。
The US startup has launched the Quip Virtual Machine (QVM), a software layer that lets developers write code once and run it across different types of quantum computers and conventional machines.
QVM可在该公司的Aglais测试网上使用，新用户可获得免费计算积分。它运行在Quip Network上，这是Postquant Labs于四月开放测试的量子计算市场。
The QVM is available on the company’s Aglais testnet, where new users receive free computing credits. It runs on Quip Network, a quantum computing marketplace that Postquant Labs opened for testing in April.
目前，主要的量子计算服务提供商都有自己的编程工具和定价系统。开发者需要了解每个系统的工作原理，并相应调整代码。Postquant Labs希望通过提供一种跨不同机器的通用方式来简化这一过程。
At the moment, major quantum computing providers have their own programming tools and pricing systems. Developers need to learn how each one works and adapt their code accordingly. Postquant Labs wants to simplify that process by providing a common way to work across different machines.
为QVM编写的程序可以在量子退火机上运行，量子退火机旨在为优化问题寻找良好解决方案，也可以在基于门的量子计算机和传统计算机上运行。
Programs written for the QVM can run on quantum annealers, which are designed to find good solutions to optimisation problems, gate-based quantum computers, and conventional computers.
“量子计算仍然分散在竞争性的指令集和汇编器之间，为外部人员提供了很少的便捷入口，”Postquant Labs首席执行官兼联合创始人Colton Dillion表示。
“Quantum computing is still fractured between competing instruction sets and assemblers, providing few easy onramps to outsiders,” said Colton Dillion, CEO and co-founder of Postquant Labs.
该公司还试图让计算成本更容易预测。其定价系统借鉴了以太坊，使用一种称为gas的单位来计算每个任务的成本。
The company is also trying to make computing costs easier to predict. Its pricing system borrows from Ethereum, using a unit called gas to calculate the cost of each job.
价格取决于所用量子比特数量、任务耗时以及所需纠缠量等因素。该公司表示，开发者在运行任务前可以看到最高成本。
The price depends on factors such as the number of qubits used, the time a job takes, and the amount of entanglement it requires. Developers can see the maximum cost before running a job, the company said.
Postquant Labs还内置了检查计算结果的方法。这些方法包括将量子输出与传统计算机上的模拟进行比较，让其他提供商验证结果，并对每个结果进行数字签名以识别产生结果的机器。
Postquant Labs has also built in ways to check computing results. These include comparing quantum outputs with simulations on conventional computers, having other providers verify results, and digitallyg each result to identify the machine that produced it.
在 Quantum.Tech World 大会上，该公司在投资组合选择任务中测试了 QVM，进行了 1930 次量子求解器与经典求解器的对比。
At the Quantum. Tech World conference, the company tested the QVM on an investment portfolio selection task, running 1,930 comparisons between quantum and classical solvers.
Postquant Labs 表示，其量子求解器在每次对比中均匹配或优于经典求解器。据该公司称，当性能差距超过 0.5% 时，中位数优势为 2.56%。
Postquant Labs said its quantum solver matched or outperformed the classical one in every comparison. When the performance gap exceeded 0.5%, the median advantage was 2.56%, according to the company.
这些结果为公司自行报告，并不确立量子计算机在投资任务上普遍优于传统计算机。
The results are company-reported and do not establish that quantum computers generally outperform conventional ones on investment tasks.
据 Postquant Labs 称，莫纳什大学、圣母大学和普渡大学的研究人员正在测试 QVM。工业 AI 公司 SiC Systems 也在探索将其用于工厂规划。
Researchers at Monash University, the University of Notre Dame, and Purdue University are testing the QVM, according to Postquant Labs. SiC Systems, an industrial AI company, is also exploring its use for factory planning.
该平台将允许开发者发布程序，并在其他人运行这些程序时赚取费用。Quip Network 全面投入运行后，用户将使用网络代币支付计算任务费用。
The platform will let developers publish programs and earn fees whenever others run them. Once Quip Network is fully operational, users will pay for computing jobs with network tokens.
Postquant Labs 还在推出 QuipSwap，这是一种旨在抵御未来量子计算机攻击的支付系统，用于处理交易。
Postquant Labs is also launching QuipSwap, a payment system designed to withstand attacks from future quantum computers, to handle transactions.
