Are we there yet? It’s still the key question about quantum computing

Image
Researchers at the University of Waterloo have made advances in quantum devices, including a fork-like silicon grating structure that generates twisted neutrons with angular momentum. Dusan Sarenac The University of Waterloo last month announced the creation of a minuscule device – so tiny it can fit more than a million times over on a grain of sugar – that twisted and expanded neutron beams into 10-centimetre-wide doughnut shapes. While most people are unlikely to care about the experimental manipulation of subatomic particles, for those immersed in quantum science the novel device was another step toward one of the ultimate goals in the field: to build a full-fledged, all-purpose quantum computer. These machines would have abilities superior to the world’s best supercomputers, and they would be able to solve problems that are currently unsolvable. The global race to build one has been less of a sprint and more of a series of small but significant steps, combined with a few leaps. “...

An Existentialist Guide to Feeling Nothing

Image
I recently watched “ the greatest film of all time ,” and the most boring one. In retrospect, the title alone should have been a sufficient warning: Jeanne Dielman, 23 Quai du Commerce, 1080 Bruxelles . Alas, I’m old enough to be a bit nostalgic about massive telephone address books. And massive it is. Clocking over 200 minutes, Chantal Akerman's 1975 dreary drama follows three days in the monotonous routine of Jeanne, a widow, a mother, and a prostitute. I watched Jeanne’s autopilot existence, until, staring at her back as she washes dishes, I decided to fast-forward a couple of minutes, only to discover she was still at it. And Jeanne is equally thorough when she’s busy baking, cleaning, folding laundry, or shining her son’s shoes. She speaks so scarcely and mechanically, that it’s impossible to detect any emotion or volition beyond her carefully controlled chores . Watching Jeanne Dielman is what the word “painstaking” was invented for. Chantal...

What Are SQL Stored Procedures and How Do You Create Them?

Image
Stored procedures: like functions for your SQL. A stored procedure is a batch of SQL statements created and stored on a database. You can reuse a stored procedure over and over again. A stored procedure can accept parameters, run a query, and return results. Many users can call a stored procedure and different applications can call it with different parameter values. What Are the Benefits of Using Stored Procedures? Apart from allowing multiple users and applications to reuse it, a stored procedure has other benefits. It is easy to modify. You can change a stored procedure when necessary and these updates will be reflected for all users. Furthermore, you don’t need to redeploy your application when you modify the stored procedure. It reduces network traffic because the server only passes the procedure’s name over the network and not the entire query. It improves database security since users don’t have direct access to tables. To make...
