LETTER FROM THE DIRECTOR CQT is ten years old and still going Our popular Generation Q Camp for quantum self-testing (pp. 42–44). This strong. Well-wishers who gathered pre-university students (pp.50–53) is just a small sample of what we're for our tenth anniversary offered both is designed to educate and inspire working on. compliments and advice. “Wah, from young minds. Our PhD and internship zero to hero, lah” commented an old programmes draw some of the brightest Even though still viewed as basic friend after visiting our labs. Ten years students. And when they leave CQT research, quantum technology is too ago, he saw just empty rooms and dusty with their hard-earned degrees, they do important to be ignored by industry. floors. “Don’t stop, even at the top”, all kinds of interesting things, quantum Through interactions with research quipped another high-ranking friend. and classical (pp.58–59). organisations, government and I was not sure how to interpret this industry, we hope to create new aspirational suggestion, so I just smiled Last year saw the usual buzz of intellectual property and new markets and mumbled. After all, where is the experimental and theoretical activities. (pp.54–57). We also pay attention to top? The field of quantum technologies We welcomed Huanqian Loh and explaining our research to the public at has expanded so much that no single Travis Nicholson, our two new Principal large (pp.74–75). institution can embrace the whole range Investigators (pp.40–41), and Charles of activities under this label. This said, Lim, a new CQT Fellow. Alexander Thus, so far so good. How about the we do have our niche. In 2017, like in Ling’s group has been working hard future? We have to both consolidate years before, we've amassed quality on their new experimental marvel and innovate. Mr Quek Gim Pew, who publications and ingenious devices, so called SpooQySat (pp.45–49). Dimitris became Chair of CQT’s Governing ticking all the boxes in our performance Angelakis’ team paired with researchers Board in 2016, shares some of his reviews. But there is more to our mission at Google to work on quantum thoughts on these issues in an interview than just dry bibliometrics. This annual simulations (pp.32–35). Our study of the (pp.15–17). Given his knowledge and report offers a glimpse of the fascinating potential impact of quantum technology experience, he is in a unique position work behind the numbers. on Bitcoin made the news (pp.36–39) to offer guidance from which we hope and our proposal for a quantum- to benefit in years to come. To start with, we've built a vibrant safe standard for cryptography was research community (pp.20–21). We accepted into a competition launched Last but not least, let me thank everyone Photo: Tan Ngiap Heng 2007 attract talented folk from all over the by the US National Institute of Standards who contributed to this report.

Truth be told, we do more Tong, a PhD student in Valerio Scarani's than welcome quantum nerds, we group, gives a nice review of work on nurture them. 2 3

In 2017, CQT expanded on the NUS campus from its base in science block S15 into the adjacent block S14 (pictured), connected by a sky bridge. The renovated space accommodates two new experimental groups (see pp.40–41) and researchers contributing to the NUS–Singtel Cyber Security R&D Lab. 4 5
