In traditional quantum learning tasks, having a larger quantum memory is an advantage as it allows for simultaneous measurements across multiple copies of quantum states. However, obtaining such a large quantum memory is not feasible for most near-term quantum devices due to current technological constraints. Researchers in a new study are exploring a novel approach that leverages less quantum memory using only two copies of a quantum state to achieve significant benefits in learning. This approach relies on constructing a complex state that includes the quantum state itself and its complex conjugate, which may lead to superior performance in certain measurements compared to traditional methods.
Through this research, it has been shown that measurements using the composite state allow for rapid results in determining fundamental quantities, such as displacement levels, with fewer samples required. This technique is innovative and opens up the field for achieving greater efficiency in quantum measurements, which is critically important in quantum research when resources are limited. The findings will enhance the scope of practical applications in areas like quantum sensing and quantum simulation, where the environment is typically noisy, which can negatively impact measurement accuracy.
What are Entangled States?
To understand the significance of this study, it is important to explain the concept of entangled states. An entangled state refers to the complex conjugate of a quantum state, and in many physical systems, this state can be easily created using well-known quantum circuits. When pairing the quantum state with its complex conjugate, it can be used to perform entangled measurements that reveal properties of quantum states effectively. The original state and its entangled copy can be likened to two pieces of a puzzle: each one alone offers useful information, but when combined, they reveal a more complete picture of the quantum system.
Research has demonstrated that learning tasks, such as identifying displacement levels, can be accomplished significantly faster using measurements on the composite state compared to traditional methods, showing the capability of this approach to drastically reduce the number of samples required. For instance, while traditional methods might require a very large number of samples, the new method can eliminate the need for many of them without impacting the accuracy of the results.
