# 英语写作重点短句和词汇示例收集

写作一直是自己的弱项，现在想要进行一个非常系统化的训练，不然文章完全写不出来。根据我自己的感受，写好文章需要具备的素质是：

- 能够自如的介绍清楚技术方面的内容，比如能够介绍清楚方程的定义、推导以及求解等，能够说清楚我们解决问题的思路以及结果。
- 能够系统的总结和概括自己文章的主要内容、创新点
- 能够对研究的动机、背景做出非常系统、简洁的描述
- 相关语句比较流畅，用词精准

这些做起来不是一蹴而就，需要多看、多学、多训练。我在这里对一些非常重要的短句、词汇以及长句表达做一些收集，便于以后写文章参考。

#### 摘要部分

Quadratic light-matter interactions are nonlinear couplings **such that** quantum emitters interact with photonic or phononic modes **exclusively** via the exchange of excitation pairs.

这句话对“Quadratic light-matter interactions”做了一个解释，用到了长句以及一些副词来修饰，解释的非常清楚到位

Implementable with atomic and solid-state systems, these couplings **lead to a plethora of phenomena** that have been characterized **in the context of** cavity QED, **where quantum emitters interact with localized bosonic modes**.

介绍这些耦合的意义，还是非常长的表述。

**We develop** a general scattering theory **under the Markov approximation** and **discuss paradigmatic examples** for spontaneous emission and scattering of biphoton states.

这是经常会用到的表达，比如，相似的还有：We propose·····

Our analytical and semianalytical **results unveil fundamental differences** with respect to conventional waveguide QED systems, such as the spontaneous emission frequency-entangled photon pairs or the full transparency of the emitter to single-photon inputs.

重点词汇：unveil

**This unlocks new opportunities in** （重点句式）quantum information processing with propagating photons.

**As a striking example**（重点句式）, we show that a single quadratically coupled emitter can implement a two-photon logic gate with unit fidelity, **circumventing a no-go theorem** derived for conventional waveguide-QED interactions

#### 背景介绍部分

The study of light-matter interactions is one of the main research pillars of quantum science.

介绍光与物质相互作用的重要性，如果是我写，肯定是：light-matter interaction is the central problem in quantum science，这里换了一个说法： main research pillars of

**The implementation of systems** where quantum emitters interact strongly with confined modes of the electromagnetic fields has allowed us to **achieve an unprecedented level of control over quantum degrees of freedom**

我之前一直想表达的一个观点：随着我们对光与物质相互作用的控制更加自如，强耦合已经可以实现，这段话就说的比较流畅

**In the framework of cavity QED**, the confinement of the electromagnetic field**makes it possible** to observe a coherent exchange of excitations between **localized photonic modes** and single quantum emitters [3]. Similarly, the **coupling of quantum emitters to propagating fields** can be strongly enhanced using waveguide structures, which **confine photons to a one-dimensional environment**

对Waveguide-QED的介绍，以Cavity-QED作为对比

This setup, known as waveguide QED, **has been realized in a variety of platforms** such as atoms [6–9] or quantum dots [10,11] coupled to photonic waveguides, **as well as** superconducting qubits [12–20] coupled to microwave transmission lines.

如何介绍、罗列多个系统

Waveguide QED structures **have a great potential to** **implement building blocks of quantum networks** [21,22], **since propagating photons are ideal to transport flying qubits over long distances while emitters can provide the strong quantum nonlinearity necessary for quantum information processing.**

这句话重要是因为其对Waveguide-QED的评价，特别是对传播光子、Emitter的作用。

Therefore, there has been intense theoretical [23–30] and experimental [31–36] research in the control and characterization of few-photon correlations generated by single quantum emitters, as well as in the implementation of photonic devices working at the few-photon level

这是对领域内的研究的一个评价，说明理论、实验都比较重要.

The rich quantum phenomenology **arising in** quadratic light-matter interactions **motivates** a fast-growing interest

如何来形容某一个领域的重要性

#### Introdution结尾部分

In this work, **we develop** a quantum optics theory to describe a single quantum emitter interacting quadratically with the photons that propagate along a one-dimensional waveguide.**We study this problem** with a two-photon scattering theory based on a Wigner-Weisskopf approach and the Born-Markov approximation.**We derive** the general form of the scattering matrix, including semianalytical solutions for arbitrary photonic input states and full analytical solutions for Gaussian inputs.**Applying this theory, we unveil observable features of** the emitter’s response that are **fundamentally different** **with respect to** conventional waveguide QED setups (see Fig. 1). These include (i) the spontaneous emission of correlated biphoton states, (ii) the strong interaction with spectrally narrow two-photon pulses, and (iii) full transparency to single-photon inputs.

Finally, we show that **these effects can be exploited in quantum information applications**, designing a deterministic controlled-phase gate that acts on pairs of propagating photons with perfect fidelity. This result seems to contradict a famous no-go theorem for photonic gates [40,79,80].

#### 正文介绍部分

It is convenient to **reparameterize** the wave function’s element using the sum and difference of photon frequencies

In this limit **one can formally solve** Eq. (5) and replace the solution into Eq. (4) to obtain

**For the sake of clarity**, let us first write the scattering relations for a fixed propagation direction of the input field along the waveguide.

#### 结尾

As demonstrated in this work, quadratic light-matter couplings **are a compelling tool to process quantum information** encoded in propagating photons.

This possibility **should be thoroughly addressed** considering each specific experimental setting, with a detailed microscopic model of the system and realistic noise sources.**The possibility of tailoring the spectral features of emitted and scattered biphoton states paves also the way to the generation of entanglement in the time-frequency domain**, **which is relevant for** quantum computation [85] and sensing [86–88] applications.
