Nowadays, it is essential to have a computer for work that involves technical aspects of any kind. Compared to a whole system, a laptop is more portable and can be used anywhere. As inflation rises and new taxes are introduced every week, laptops are becoming increasingly costly, especially in Pakistan. When you have a small budget, it’s difficult to find a good laptop, and if you’re really tight on cash, I recommend choosing PCs instead of laptops.

We have compiled a list of affordable laptops under Rs150k. You are sure to find the laptop you are looking for among these.

Acer Aspire 3

The Acer Aspire 3 laptops are seen in the lower to mid-range segment, despite Acer’s reputation for high-spec gaming laptops. These laptops are especially useful for studying, watching movies, surfing the internet, and even using Photoshop. It features an Intel Core i5 processor and 8GB RAM, allowing you to multitask with basic programs like Microsoft Office. There is an Intel Core i5 processor, 8GB of RAM, and 512GB of storage on these laptops. The Acer runs whatever you can run on the laptop without slowing down even when there are multiple programs running simultaneously.

Dell Inspiron 15

This Dell Inspiron 15 3000 (3511) has 4GB of RAM, 128GB of solid-state storage, and an Intel Core i3-1115G4 processor. The graphics and memory are not up to a decent laptop’s standards, but the processor is still a step above another cheap laptop’s Celeron CPU.

Dell Vostro 15 3510

This Vostro 15 3510 is made entirely of plastic, which is not surprising considering the majority of Vostro models are plastic-bodied. There are a lot of processor options available with this notebook. There are Celeron 6305s, Pentium 7505s, Core i3-1005G1s, Core i5-1035G1s, Core i3-1115G4s, Core i3-1125G4s, Core i5-1135G7s, and Core i7-1165G7s that you can choose from, and the more expensive the processor that you choose, the more expensive it will be. This laptop comes with a strong battery and a 41Wh battery that will last for 7 hours and 5 minutes when browsing the web, or for 6 hours and 30 minutes when watching videos.

Lenovo Thinkbook 15 G2

This Lenovo ThinkBook uses an Intel Core i5-1135G7 processor with an Intel Iris Xe Graphics G7 80EUs integrated graphics unit. It comes with 16 GB of RAM and 512 GB of SSD, and Lenovo has removed the USB-A port that was hidden behind a flap in the first generation of the ThinkBook 15. However, one of the USB-C ports supports Thunderbolt 4, which allows for a number of expansion options. Also, the separate power connector has been removed, so it can now be charged via a USB-C port. Its display is a 15.6-inch IPS panel that provides a 1920 x 1080 resolution.

HP 15s

Hp 15s

It is a budget-friendly mid-range laptop that offers substantial savings over its competition, making it a great choice for students and office workers who are currently on a tight budget. In the HP 15s, the same Intel Core i5-1135G7 processor powering the 17-inch HP 17 as well as 8GB of RAM, a 256GB solid-state drive, and an Intel Iris Xe graphics card are featured.

Google touts new method for quantum error correction

Three years ago, Google announced that it had achieved “quantum advantage,” meaning that it had achieved results on a quantum computer that would not have been possible with a classical supercomputer. However, since then, Google has been relatively quiet about its progress in the quantum computing space, with few updates on its achievements and ambitions. In contrast, many quantum start-ups have been announcing funding, executive appointments, new products, and technology innovations on a daily basis for the last two to three years.

Nevertheless, Google’s CEO Sundar Pichai announced this week that the company had achieved a major milestone in the field of error correction for quantum computers. For the first time, Google’s Quantum AI researchers have experimentally demonstrated that it’s possible to reduce errors by increasing the number of qubits. Qubits are the basic units of quantum information that can take on richer states beyond just 0 and 1. Google’s breakthrough represents a significant shift in how quantum computers operate.

Rather than working on the physical qubits on the quantum processor one by one, researchers are treating a group of them as one logical qubit. As a result, a logical qubit made from 49 physical qubits outperformed one made from 17 qubits. This is significant because the race to build viable quantum computers so far has largely been a race for more qubits to increase the potential computing power of quantum machines. However, the error rates of today’s quantum computers are not sufficient for the use cases that are developing for them.

Google’s latest contribution to the field of quantum error correction, outlined in Nature, is promising because it demonstrates the “scaling of logical qubits” that are needed to improve accuracy, in part by increasing the size of the quantum “surface code” used. Pichai explained that by encoding larger numbers of physical qubits on the quantum processor into one logical qubit, Google hopes to reduce the error rates to enable useful quantum algorithms.

Google’s latest breakthrough in quantum error correction is a significant milestone that could help bridge the gap between the current state of quantum computing and its potential. It demonstrates the potential for reducing errors in quantum computing by increasing the number of qubits and using a logical approach. While many other companies are also investing in quantum error correction, Google’s contribution is promising and could bring us closer to the development of useful quantum algorithms.
