More than 40 million Americans move each year, but not always by choice. Whether you’re moving because of work or schooling or for better chances, adjusting to (适应) the life in a new place can be difficult. 【小题1】. Here are some tips to help you adjust to your new home.

【小题2】. So stay positive and get out there and explore! Taste the local food and visit famous places and museums. Try local activities that aren’t popular in your former city, such as skating if you come from a beach town or surfing if you lived in the mountains. You may discover a talent (才华) or interest you never knew you had.

Introduce yourself to neighbors and everyone else you meet. 【小题3】. This is the best way to get advice about living in your area, and to make new friends. Attend local events that interest you, visit the markets or yard sales, take classes and so on. All of these things will help you meet people and feel connected.

【小题4】

It takes time to get to know a new place, so don’t expect to feel comfortable right away. 【小题5】. To help make the process easier, you can meet new people, find a support group near you. A fresh move is also a fresh start. Therefore it is a great time to start realizing a dream you’ve had, whether it is going back to school, starting a new career, or finishing a novel.

Have you ever felt the urge to input critical financial information on a not-so-familiar business’s website? Would you dare to entrust your credit card details or passwords to potentially unsafe trading platforms?

Researchers from the University of Vienna have tackled this dilemma by designing an unconditionally secure system for conducting trade in such situations. This solution is “quantum (量子)-digital payments” which combines crystallographic (加密的) methods with the properties of quantum light.

In today’s payment ecosystem, customers’ sensitive data is replaced by sets of random numbers, and the uniqueness of each trade is secured by a classical crystallographic method. However, companies with powerful computational resources can break these codes and recover the customers’ private data, and for example, make payments in their name.

A research team led by professor Philip Walther from the University of Vienna has shown how the quantum properties of light can ensure security for digital payments. In an experiment, the researchers demonstrated that each trade cannot be copied. They replaced classical crystallographic techniques with a quantum protocol (协议) using single photons, a unit of energy. During the course of a classical digital payment trade, the client shares a classical code called cryptogram with his payment provider. This cryptogram is then passed on between the customer, businessmen, and payment provider. In the demonstrated quantum protocol this cryptogram is generated by having the payment provider sending particularly prepared single photons to the client.

The researchers successfully conducted quantum-digital payments,connecting two university buildings in downtown Vienna. Digital payments currently operate within a few seconds. “At present, our protocol takes a few minutes of quantum communication to complete a trade. This is to guarantee security in the presence of noise and losses,” says Philip Walther. “However, these time limitations are only of technological nature. We will witness that quantum-digital payments reach practical performance in the very near future. ”
